Quanting and issue 37

[mike]

Hey all,

I am trying to understand beam-quanting.cc better, and I think I know how I'm 
gonna tackle this.

I'm going to put my collision callback before beam quanting, and then try 
something to the effect of:

if (the beam was pushed up during the collision callback)
  impose an insanely prohibitive demerit for the beam position going down in 
the quanting
else if (the beam was pushed down during the collision callback)
  impose an insanely prohibitive demerit for the beam position going up in the 
quanting

Could anyone give me a quick primer on how to do that?

Cheers,
MS
