/*
 * AF2DfltTriangleRules.hpp
 *
 * \brief An AF2DfltTriangleRules defines a default set of rules to
 * use for a two-dimensional advancing front triangle-meshing algorithm.
 *
 * Constructing an instance of AF2DfltTriangleRules constructs all of
 * associated default rules.  The AF2DfltTriangleRules retains ownership
 * of the rule objects until it is deleted, so if any subset of the rules
 * from an instance of AF2DfltTriangleRules are used in an AF2Algorithm,
 * the context should ensure that the instance of AF2DfltTriangleRules
 * remains in memory.
