-/**
- * A BasicSourceMapConsumer instance represents a parsed source map which we can
- * query for information about the original file positions by giving it a file
- * position in the generated source.
- *
- * The first parameter is the raw source map (either as a JSON string, or
- * already parsed to an object). According to the spec, source maps have the
- * following attributes:
- *
- *   - version: Which version of the source map spec this map is following.
- *   - sources: An array of URLs to the original source files.
- *   - names: An array of identifiers which can be referrenced by individual mappings.
- *   - sourceRoot: Optional. The URL root from which all sources are relative.
- *   - sourcesContent: Optional. An array of contents of the original source files.
- *   - mappings: A string of base64 VLQs which contain the actual mappings.
- *   - file: Optional. The generated file this source map is associated with.
- *
- * Here is an example source map, taken from the source map spec[0]:
- *
- *     {
- *       version : 3,
- *       file: "out.js",
- *       sourceRoot : "",
- *       sources: ["foo.js", "bar.js"],
- *       names: ["src", "maps", "are", "fun"],
- *       mappings: "AA,AB;;ABCDE;"
- *     }
- *
- * The second parameter, if given, is a string whose value is the URL
- * at which the source map was found.  This URL is used to compute the
- * sources array.

-/**
- * An IndexedSourceMapConsumer instance represents a parsed source map which
- * we can query for information. It differs from BasicSourceMapConsumer in
- * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
- * input.
- *
- * The first parameter is a raw source map (either as a JSON string, or already
- * parsed to an object). According to the spec for indexed source maps, they
- * have the following attributes:
- *
- *   - version: Which version of the source map spec this map is following.
- *   - file: Optional. The generated file this source map is associated with.
- *   - sections: A list of section definitions.
- *
- * Each value under the "sections" field has two fields:
- *   - offset: The offset into the original specified at which this section
- *       begins to apply, defined as an object with a "line" and "column"
- *       field.
- *   - map: A source map definition. This source map could also be indexed,
- *       but doesn't have to be.
- *
- * Instead of the "map" field, it's also possible to have a "url" field
- * specifying a URL to retrieve a source map from, but that's currently
- * unsupported.
- *
- * Here's an example source map, taken from the source map spec[0], but
- * modified to omit a section which uses the "url" field.
- *
- *  {
- *    version : 3,
- *    file: "app.js",
- *    sections: [{
- *      offset: {line:100, column:10},
- *      map: {
- *        version : 3,
- *        file: "section.js",
- *        sources: ["foo.js", "bar.js"],
- *        names: ["src", "maps", "are", "fun"],
- *        mappings: "AAAA,E;;ABCDE;"
- *      }
- *    }],
- *  }
- *
- * The second parameter, if given, is a string whose value is the URL
- * at which the source map was found.  This URL is used to compute the
- * sources array.
- *

+ * already parsed to an object). According to the spec, source maps have the
+ * following attributes:
+ *
+ *   - version: Which version of the source map spec this map is following.
+ *   - sources: An array of URLs to the original source files.
+ *   - names: An array of identifiers which can be referrenced by individual mappings.
+ *   - sourceRoot: Optional. The URL root from which all sources are relative.
+ *   - sourcesContent: Optional. An array of contents of the original source files.
+ *   - mappings: A string of base64 VLQs which contain the actual mappings.
+ *   - file: Optional. The generated file this source map is associated with.
+ *
+ * Here is an example source map, taken from the source map spec[0]:
+ *
+ *     {
+ *       version : 3,

+/**
+ * An IndexedSourceMapConsumer instance represents a parsed source map which
+ * we can query for information. It differs from BasicSourceMapConsumer in
+ * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
+ * input.
+ *
+ * The first parameter is a raw source map (either as a JSON string, or already
+ * parsed to an object). According to the spec for indexed source maps, they
+ * have the following attributes:
+ *
+ *   - version: Which version of the source map spec this map is following.
+ *   - file: Optional. The generated file this source map is associated with.
+ *   - sections: A list of section definitions.
+ *
+ * Each value under the "sections" field has two fields:
+ *   - offset: The offset into the original specified at which this section
+ *       begins to apply, defined as an object with a "line" and "column"
+ *       field.
+ *   - map: A source map definition. This source map could also be indexed,
+ *       but doesn't have to be.
+ *
+ * Instead of the "map" field, it's also possible to have a "url" field
+ * specifying a URL to retrieve a source map from, but that's currently
+ * unsupported.
+ *
+ * Here's an example source map, taken from the source map spec[0], but
+ * modified to omit a section which uses the "url" field.
+ *
+ *  {
+ *    version : 3,
+ *    file: "app.js",
+ *    sections: [{
+ *      offset: {line:100, column:10},
+ *      map: {
+ *        version : 3,
+ *        file: "section.js",
+ *        sources: ["foo.js", "bar.js"],
+ *        names: ["src", "maps", "are", "fun"],
+ *        mappings: "AAAA,E;;ABCDE;"
+ *      }
+ *    }],
+ *  }
+ *
+ * The second parameter, if given, is a string whose value is the URL
+ * at which the source map was found.  This URL is used to compute the
+ * sources array.
+ *
+ * [0]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit#heading=h.535es3xeprgt

-/**
- * A BasicSourceMapConsumer instance represents a parsed source map which we can
- * query for information about the original file positions by giving it a file
- * position in the generated source.
- *
- * The first parameter is the raw source map (either as a JSON string, or
- * already parsed to an object). According to the spec, source maps have the
- * following attributes:
- *
- *   - version: Which version of the source map spec this map is following.
- *   - sources: An array of URLs to the original source files.
- *   - names: An array of identifiers which can be referrenced by individual mappings.
- *   - sourceRoot: Optional. The URL root from which all sources are relative.
- *   - sourcesContent: Optional. An array of contents of the original source files.
- *   - mappings: A string of base64 VLQs which contain the actual mappings.
- *   - file: Optional. The generated file this source map is associated with.
- *
- * Here is an example source map, taken from the source map spec[0]:
- *
- *     {
- *       version : 3,
- *       file: "out.js",
- *       sourceRoot : "",
- *       sources: ["foo.js", "bar.js"],
- *       names: ["src", "maps", "are", "fun"],
- *       mappings: "AA,AB;;ABCDE;"
- *     }
- *
- * The second parameter, if given, is a string whose value is the URL
- * at which the source map was found.  This URL is used to compute the
- * sources array.
- *
- * [0]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit?pli=1#

-/**
- * An IndexedSourceMapConsumer instance represents a parsed source map which
- * we can query for information. It differs from BasicSourceMapConsumer in
- * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
- * input.
- *
- * The first parameter is a raw source map (either as a JSON string, or already
- * parsed to an object). According to the spec for indexed source maps, they
- * have the following attributes:
- *
- *   - version: Which version of the source map spec this map is following.
- *   - file: Optional. The generated file this source map is associated with.
- *   - sections: A list of section definitions.
- *
- * Each value under the "sections" field has two fields:
- *   - offset: The offset into the original specified at which this section
- *       begins to apply, defined as an object with a "line" and "column"
- *       field.
- *   - map: A source map definition. This source map could also be indexed,
- *       but doesn't have to be.
- *
- * Instead of the "map" field, it's also possible to have a "url" field
- * specifying a URL to retrieve a source map from, but that's currently
- * unsupported.
- *
- * Here's an example source map, taken from the source map spec[0], but
- * modified to omit a section which uses the "url" field.
- *
- *  {
- *    version : 3,
- *    file: "app.js",
- *    sections: [{
- *      offset: {line:100, column:10},
- *      map: {
- *        version : 3,
- *        file: "section.js",
- *        sources: ["foo.js", "bar.js"],
- *        names: ["src", "maps", "are", "fun"],
- *        mappings: "AAAA,E;;ABCDE;"
- *      }
- *    }],
- *  }
- *
- * The second parameter, if given, is a string whose value is the URL
- * at which the source map was found.  This URL is used to compute the
- * sources array.
- *
- * [0]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit#heading=h.535es3xeprgt

+ *   - sourcesContent: Optional. An array of contents of the original source files.
+ *   - mappings: A string of base64 VLQs which contain the actual mappings.
+ *   - file: Optional. The generated file this source map is associated with.
+ *
+ * Here is an example source map, taken from the source map spec[0]:

+ * An IndexedSourceMapConsumer instance represents a parsed source map which
+ * we can query for information. It differs from BasicSourceMapConsumer in
+ * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
+ * input.
+ *
+ * The first parameter is a raw source map (either as a JSON string, or already
+ * parsed to an object). According to the spec for indexed source maps, they
+ * have the following attributes:
+ *
+ *   - version: Which version of the source map spec this map is following.
+ *   - file: Optional. The generated file this source map is associated with.
+ *   - sections: A list of section definitions.
+ *
+ * Each value under the "sections" field has two fields:
+ *   - offset: The offset into the original specified at which this section
+ *       begins to apply, defined as an object with a "line" and "column"
+ *       field.
+ *   - map: A source map definition. This source map could also be indexed,
+ *       but doesn't have to be.
+ *
+ * Instead of the "map" field, it's also possible to have a "url" field
+ * specifying a URL to retrieve a source map from, but that's currently
+ * unsupported.
+ *
+ * Here's an example source map, taken from the source map spec[0], but
+ * modified to omit a section which uses the "url" field.
+ *
+ *  {
+ *    version : 3,
+ *    file: "app.js",
+ *    sections: [{
+ *      offset: {line:100, column:10},
+ *      map: {
+ *        version : 3,
+ *        file: "section.js",
+ *        sources: ["foo.js", "bar.js"],
+ *        names: ["src", "maps", "are", "fun"],
+ *        mappings: "AAAA,E;;ABCDE;"
+ *      }
+ *    }],
+ *  }
+ *
+ * The second parameter, if given, is a string whose value is the URL
+ * at which the source map was found.  This URL is used to compute the
+ * sources array.
+ *
+ * [0]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit#heading=h.535es3xeprgt
