* Need to read article on ion velocity distribution and adjust simulations accordingly. Currently the GPT uses a random velocity distribution...maybe there is a better way to do it?
* Uploaded Reiser chapter and Rieke/Prepejchal article on ionization cross sections. Will upload Binary Encounter Dipole Model for secondary electron differential cross sections.
