CrossedOther

Procs for the atom on the other side of Crossed, Uncrossed, and Bump.
This library overrides the following procs to work:

• atom.Crossed(M) calls M.CrossedOther(atom)
• atom.Uncrossed(M) calls M.UncrossedOther(atom)
• movable.Bump(A) calls A.BumpedBy(movable)

If you override any of these procs, be sure to call ..() for the other side's effect to be called.

Performance
This library adds overrides to the base atomic types. Whenever any atom is crossed, uncrossed, or bumped, these procs are called, adding overhead to most movements.
