inning of run
               (2) desired T at end of run
               (3) check for rescaling every this many timesteps
               (4) T window outside of which velocities will be rescaled
               (5) fractional amount (0.0 to 1.0) of rescaling to perform
         replace
               (1) desired T at beginning of run
               (2) desired T at end of run
               (3) do Gaussian replacement every this many timesteps
               (4) random # seed to use for replacement (0 < seed
