cross check dll/opencl/python polydispersity and orientation results (Trac #953)

[pkienzle]

Implement 1D/2D versions symmetric and asymmetric particles in pure python so that we can cross check the polydispersity calculations in the three different implementations of the polydispersity loop.

Ellipsoid and triaxial ellipsoid for example.
