JSON support

Gosu has native support for JavaScript Object Notation (JSON) data format. JSON is an open-standard format that uses human-readable text to transmit data objects consisting of attribute-value pairs, hierarchical data structures, and arrays. Web sites often send or receive small amounts of JSON data as a lightweight alternative to the XML standard. Creation of JSON data and parsing can be implemented in any language or operating system, and is especially popular due to efficient web browser client-side parsing in JavaScript.
