/**
* HandleMessage() is a function that the browser calls when PostMessage()
* is invoked on the DOM element for the module instance in JavaScript. Note
* that PostMessage() in the JavaScript interface is asynchronous, meaning
* 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 which has been converted from a
* JavaScript value. JavaScript array/object types are supported from Chrome
* M29 onward. All JavaScript values are copied when passing them to the
* plugin.
*
* When converting JavaScript arrays, any object properties whose name
* is not an array index are ignored. When passing arrays and objects, the
* entire reference graph will be converted and transferred. If the reference
* graph has cycles, the message will not be sent and an error will be logged
* to the console.
*
* 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
