/**
* The require function conforming to CommonJS spec:
* http://wiki.commonjs.org/wiki/Modules/1.1.1
*
* To define a CommonJS-compliant module add the providesModule
* Haste header to your file instead of @provides. Your file is going
* to be executed in a separate context. Every variable/function you
* define will be local (private) to that module. To export local members
* use "exports" variable or return the exported value at the end of your
* file. Your code will have access to the "module" object.
* The "module" object will have an "id" property that is the id of your
* current module. "module" object will also have "exports" property that
* is the same as "exports" variable passed into your module context.
* You can require other modules using their ids.
*
* Haste will automatically pick dependencies from require() calls. So
* you don't have to manually specify @requires in your header.
*
* You cannot require() modules from non-CommonJS files. Write a legacy stub
* (@providesLegacy) and use @requires instead.
*
* @example
*
* / **
* * @providesModule math
* * /
* exports.add = function() {
* var sum = 0, i = 0, args = arguments, l = args.length;
* while (i < l) {
* sum += args[i++];
* }
* return sum;
* };
*
* / **
* * @providesModule increment
* * /

*
* On the other hand there are modules, that you can call "entrance points".
* You want to run the "factory" method for them as soon as all dependencies
* are met.
*
* @example
*
* define('BaseClass', [], function() { return ... });
* // ^^ factory for BaseClass was just stored in modulesMap
*
* define('SubClass', ['BaseClass'], function() { ... });
* // SubClass module is marked as ready (waiting == 0), factory is just
* // stored
*
* define('OtherClass, ['BaseClass'], function() { ... });
* // OtherClass module is marked as ready (waiting == 0), factory is just
* // stored
*
* requireLazy(['SubClass', 'ChatConfig'],
* function() { ... });
* // ChatRunner is waiting for ChatConfig to come
*
* define('ChatConfig', [], { foo: 'bar' });
* // at this point ChatRunner is marked as ready, and its factory
* // executed + all dependent factories are executed too: BaseClass,
* // SubClass, ChatConfig notice that OtherClass's factory won't be
