Made spike at E0 more visible in plot
Scratching
Some changes in input parameters
Split helpers module into physics and random modules
Added additional methods of energy sharing
Minor changes to simulation.
Scratched some more
Added IO module and renamed simulation module
Changes in input parameters to program
I scratch your back...
Further development of simulation

* Split some modules, and added some
* Cross-section interpolation
* Maybe-working energy splitting from cs
* Timestamped output for history-keeping
...you scratch mine?
Added test file to make sure cross section interpolation works
