Usage: 

 -d x      : rest density (default 1000kg) 
 -r x      : particle radius (default 0.1m)
 -m x      : viscosity (default 0.0007)
 -t x      : timestep (default 0.0004 s)
 -s  path  : save frames in folder path
 -p  path  : save plot data in folder path
 -l x      : sim time between frames saved (default 0.033 sec)
 -w x      : sim time to run for (default 5 sec)
 -e path   : convert .bin to .txt onto stdout
 -c x      : room width (default 0.6)
 -n x      : number of particles to limit to
 -v        : use sdt::vector instead of spatial hash map
