CS = CoordinateSystem()
drawAxes(CS)

The axes are not correctly drawn:
1) the BACK faces triangles are not visible
2) in addition to the 3 positive axes, the 3 additional negative axes are also displayed. The negative axes should probably not be displayed.

In addition, I would have 2 feature requests:

3) add a CoordinateSystem.checkOrtho() to return True/False when the coordinate system is/isn't orthogonal. And checkCartesian to check that is orthoginal and normalized.

4) instead of drawing a CoordinateSystem using drawAxes, could we define a method like: CoordinateSystem.draw() ? I do realise this could have a big impact.
