USAGE AND INPUT:
electron/stopping/fit: Calculates electronic stopping power and
cumulative energy lost to the electron gas via a quadratic
functional and applies a drag force to the classical equations
of motion for atoms moving above some cutoff velocity.
Usage : fix edrag all electron/stopping/fit 4.63 3.3e-3 4.0e-8
Input : - Lower energy cutoff (Upper cutoff is assumed
to be 2x this value for truncation)
- Linear coefficient
- Quadratic coefficient (Usually taken = 0)
