Operations
bool	operator() (const Edge_profile::FT &current_cost, const Edge_profile &profile, const Edge_profile::edges_size_type initial_edge_count, const Edge_profile::edges_size_type current_edge_count) const
	This predicate is called each time an edge is selected for processing, before it is collapsed.

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.
