small typo

import xrt.backends.raycing.materials as rm
crystal = rm.CrystalSi(hkl=(1,1,1))
crystal.name

I guess the CrystalSi inherited from Diamond, but the name should be "Silicon"?

Hi,
You're right, this problem existed but was fixed about two months ago in the GitHub code.
Very soon we will release a new version.
Thanks for reporting!
