/*
 * AF2RuleExistEdge.hpp
 *
 * A specification of an edge that must exist in order for a rule to
 * be applied.
 *
 * Note that the vector difference referred to in this class is the
 * second endpoint minus the first endpoint.  The order of the points
 * also matters when testing whether an actual edge matches this
 * specification.  The points should be ordered so that the region that
 * still needs to be meshed is to the left, i.e., ordered in a
 * counterclockwise traversal of the boundary of the unmeshed region.
