// The Module object: Our interface to the outside world. We import
// and export values on it, and do the work to get that through
// closure compiler if necessary. There are various ways Module can be used:
// 1. Not defined. We create it here
// 2. A function parameter, function(Module) { ..generated code.. }
// 3. pre-run appended it, var Module = {}; ..generated code..
// 4. External script tag defines var Module.
// We need to do an eval in order to handle the closure compiler
// case, where this code here is minified but Module was defined
// elsewhere (e.g. case 4 above). We also need to check if Module
// already exists (e.g. case 3 above).
// Note that if you want to run closure, and also to use Module
// after the generated code, you will need to define   var Module = {};
// before the code. Then that object will be used in the code, and you
// can continue to use Module afterwards as well.
