/**
@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 -> 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.)
JSON numbers turn into NSDecimalNumber instances,
as we can thus avoid any loss of precision. (JSON allows ridiculously large numbers.)
