Title: Minor tweaks to make it a better example. Added proper array-style target addressing and matrix support to the ColladaLoader

Removed extraneous work in setting up the animation loop. Added support for array-style target addressing according to COLLADA spec. Added support for matrix transform updates. Added support for hierarchical animations as defined in COLLADA spec (Credit to ekitson).

I believe I got the style and your tweaks from the top of dev. Thanks
