Utility library for interactive media development

/**
 * a regex for identifying the keys within a property path, captured via the named group 'key'
 * additional named groups capture notation before/after key, e.g. ['someProp'] would capture [' and '] (before/after)
 * and the final named group 'type' captures any characters bewteen 'key' and 'after', e.g. .someProp[] would capture []
 * @todo look at limiting keys to valid identifier characters when unquoted
