CGAL 5.6.1  Triangulated Surface Mesh Simplification

The concept StopPredicate
describes the requirements for the predicate which indicates if the simplification process must finish.

This predicate is called each time an edge is selected for processing, before it is collapsed.
current_edge_cost
is the cost of the selected edge. initial_edge_count
and current_edge_count
are the number of initial and current edges. If the return value is true
the simplification terminates before processing the edge, otherwise it continues normally.
