* HandleMessage() is a function that the browser calls when PostMessage()

* JavaScript execution will not be blocked while HandleMessage() is
* processing the message.
*
* @param[in] instance A PP_Instance identifying one instance
* of a module.
* @param[in] message A PP_Var containing the data to be sent
* to JavaScript. Message can have an int32_t, double, bool, or string value
* (objects are not supported).
*
* The following JavaScript code invokes HandleMessage, passing
* the module instance on which it was invoked, with message
* being a string PP_Var containing "Hello world!"
*
* Example:
*
* @code
*
*

* @endcode
