Update DiffuseMaterial.java
Overhaul of the exporter.
- Moved AWD, OBJ, and Serialization export methods into classes and created extensible framework for general exporting.
- Removed superfluous serializeOBJ methods as they are redundant.
- Added code examples and class documentation to AWD parsing and other related classes.
- Updated class documentation for some of the various classes I have written.
Curves overhaul. Renamed classes and moved them into the "curves" sub package from the "animation" package.
Also added a Quadratic Bezier Curve, a Linear Bezier Curve and a Compound Curve.
