/**
@page json2objc JSON to Objective-C
JSON is mapped to Objective-C types in the following way:
@li null -> NSNull
@li string -> NSString
@li array -> NSMutableArray
@li object -> NSMutableDictionary
@li true -> NSNumber's -numberWithBool:YES
@li false -> NSNumber's -numberWithBool:NO
@li integer up to 19 digits -> NSNumber's -numberWithLongLong:
@li all other numbers -> NSDecimalNumber
Since Objective-C doesn't have a dedicated class for boolean values,
these turns into NSNumber instances. However, since these are
initialised with the -initWithBool: method they round-trip back to JSON
properly. In other words, they won't silently suddenly become 0 or 1;
they'll be represented as 'true' and 'false' again.
As an optimisation integers up to 19 digits in length (the max length
for signed long long integers) turn into NSNumber instances, while
complex ones turn into NSDecimalNumber instances. We can thus avoid any
loss of precision as JSON allows ridiculously large numbers.
@page objc2json Objective-C to JSON
Objective-C types are mapped to JSON types in the following way:
@li NSNull -> null
@li NSString -> string
@li NSArray -> array
@li NSDictionary -> object
@li NSNumber's -initWithBool:YES -> true
@li NSNumber's -initWithBool:NO -> false
@li NSNumber -> number
@note In JSON the keys of an object must be strings. NSDictionary
keys need not be, but attempting to convert an NSDictionary with
non-string keys into JSON will throw an exception.
NSNumber instances created with the -numberWithBool: method are
converted into the JSON boolean "true" and "false" values, and vice
versa. Any other NSNumber instances are converted to a JSON number the
way you would expect.
