/**
@brief The JSON parser class.
JSON is mapped to Objective-C types in the following way:
@li Null -> NSNull
@li String -> NSMutableString
@li Array -> NSMutableArray
@li Object -> NSMutableDictionary
@li Boolean -> NSNumber (initialised with -initWithBool:)
@li Number -> (NSNumber | NSDecimalNumber)
Since Objective-C doesn't have a dedicated class for boolean values, these turns into NSNumber
instances. These are initialised with the -initWithBool: method, and
round-trip back to JSON properly. (They won't silently suddenly become 0 or 1; they'll be
represented as 'true' and 'false' again.)
As an optimisation short JSON 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.
