/**
 * mjson - modified json parser
 * syntax changes:
 *   - no {} needed around the whole file
 *   - "=" is allowed instead of ":"
 *   - quotes around the key are optional
 *   - commas after values are optional
 *   - and c-style comments allowed
 *
 * intermediate storage is based on ideas from BJSON specification: http://bjson.org
 *
 * some code ideas are borrowed from another json parser: https://github.com/megous/sjson
