Detailed Description

Abstract base class. Concrete implementations know how to cut a cell (i.e. determine a loop around the circumference).

Loop around the cell is given as the vertices to be cut and edges to be cut (and a weight between 0 and 1 giving where the cut is to be made). Main routine is 'cut' which gets called for every cell and gets the current cut situation and expects to return a loop on the cell circumference.

Calling function needs to determine whether cellLooper is compatible with existing set of cuts.

Also contains various utility functions which implementations might want to use.
