SymSim

This package is a rudimentary simulation tool based on kinematic scattering of clusters. While not completely correct this package gives basic planar diffraction patterns with some symmetry and allows for rotation (2 and 3-D rotations) as well as allowing for disorder (Debye-Waller factor).

As a result this package should be taken with a grain of salt. It is interesting for understanding the effects of different symmeteries on Angular Correlations, FEM, and other 4-D STEM methods because it is a direct understanding of these effects. The Kinematics are correct assuming that all of the diffraction spots hav an intensity = 1 if they are on he Ewald sphere and they are off the further they get from the ideal diffraction case.

Let me know if there are any issues and I will work to fix the mistakes.
