[x3d-public] SAI for scaling Humanoids

[John Carlson]

8.  Do code reuse as much as possible, use stylesheet for generating
methods inside X3DJSAIL for scaled HAnim XML output and possible matrix
multipliers.   Look at how Xj3D multiplies matrices.

9. develop code to convert matrix back to translation, scale, rotation, if
we need a Transform.
