/**
* @constructor
* Defines a GreenSock class, optionally with an array of dependencies that must be instantiated first and passed into the definition.
* This allows users to load GreenSock JS files in any order even if they have interdependencies (like CSSPlugin extends TweenPlugin which is
* inside TweenLite.js, but if CSSPlugin is loaded first, it should wait to run its code until TweenLite.js loads and instantiates TweenPlugin
* and then pass TweenPlugin to CSSPlugin's definition). This is all done automatically and internally.
*
* Every definition will be added to a "com.greensock" global object (typically window, but if a window.GreenSockGlobals object is found,
* it will go there as of v1.7). For example, TweenLite will be found at window.com.greensock.TweenLite and since it's a global class that should be available anywhere,
* it is ALSO referenced at window.TweenLite. However some classes aren't considered global, like the base com.greensock.core.Animation class, so
* those will only be at the package like window.com.greensock.core.Animation. Again, if you define a GreenSockGlobals object on the window, everything
* gets tucked neatly inside there instead of on the window directly. This allows you to do advanced things like load multiple versions of GreenSock
* files and put them into distinct objects (imagine a banner ad uses a newer version but the main site uses an older one). In that case, you could
* sandbox the banner one like:
*
*
*
*
*
*
*
* @param {!string} ns The namespace of the class definition, leaving off "com.greensock." as that's assumed. For example, "TweenLite" or "plugins.CSSPlugin" or "easing.Back".
* @param {!Array.} dependencies An array of dependencies (described as their namespaces minus "com.greensock." prefix). For example ["TweenLite","plugins.TweenPlugin","core.Animation"]
* @param {!function():Object} func The function that should be called and passed the resolved dependencies which will return the actual class for this definition.
* @param {boolean=} global If true, the class will be added to the global scope (typically window unless you define a window.GreenSockGlobals object)
