// Description: This file contains the class definition for RCM.
// RCM is an object to perform the Reverse Cuthill-McKee numbering
// scheme on the vertices of a graph. This is done by invoking the
// number() method with the Graph to be numbered.
//
// Side effects: numberer() changes the Tmp values of the vertices to
// the number assigned to that vertex.
//
// What: "@(#) RCM.h, revA"
