Canvas 3d JS Library

Finished writing unit tests for Vector, Matrix, and MathHelper. Those are the only files that have math in them. The rest need some fancier testing than the ok(a==b) I’ve done so far. Not sure we’re going to do that or not. I think I found 3 problems: inverseMatrix(), matrixDeterminant(), and MatrixAdjoint() don’t seem to work. Either that or I don’t know how to use them properly. Would be great if Mark or Andor had a look at those. The test is in test_CRDAPI.html. It’s almost readable. I marked the lines with the problems with ‘!!’. In fact you should have a look at the rest of it as well - since I assumed the rest of the functions do work properly, and used the data returned by them for the unit tests. Better not get test failures when broken code is fixed
