Fixed random velocity setting.
Fixed particle radius (was using it as diameter). Save as SVG. Prob3 square looks better.
Fixed particle radius (was treating as diameter). Fixed Fp max calc. +Class to hold stats. +Timing. +Save as SVG.
Fp max is now calculated as the max before a drop of a certain magnitude. This fixes behavior for small sleds with negative W.
+Plot of friction slope and aggregated Fp. Fixed Fp max calc, for real this time. Added CSV printout.
Fixed friction plot to show fitted line. Cleaned.
Whoops
Added (un)pickling of stats list.
Renames and nicer plots.
Distance matrix of one point now supported.
+Neighbor list implementation using KDTree - works but bad perf. Working on kd sparse matrix LJ.
NOTE: run_func for sim is set to None so we can just run 1 step of the sim for perf testing.
Link to setup in linux.
