Class to hold a collection of JSON key:value pairs.
Public interface
A JsonKVMap object is the result of a JSON file parsed by JsonParser. It is a map of name to a JsonValue object holding an arbitrary value (including a JsonKVMap for nested structs).
JsonKVMap has functions to test if a given field is present and to get its JsonValue. It also has functions to get a scalar value where a default value is used if the key is undefined.
JsonKVMap is derived from std::map, so all its functions are available. Iterators make standard iteration possible.
JSON is a commonly used interchange format.
