+Python module for interacting with the Zenoss API an an object-oriented way.
+The philosophy here is to use objects to work with everything in the Zenoss 
+API, and to try to normalize the various calls to the different routers.
+Thus `get` methods will always return an object, `list` methods will return 
+data. All methods to add or create start with `add`, all remove or delete 
+start with `delete`. As much as possible the methods try to hide the 
+idiosyncrasies of the JSON API, and to do the work for you, for example 
+by letting you use a device name instead of having to provide the full 
+device UID for every call.
