// Purpose: This file contains the class definition for GlueNodeToElement.
// GlueNodeToElement is a class which stores the information for a multiple
// retained nodes constraint. A multifreedom constraint relates certain dofs at 
// a constrained node to be related to certains dofs at multiple retained nodes:

// The GlueNodeToElement class assumes time invariant constraints, i.e. the
// constraint matrix does not change over time. All the methods are declared
// as pure virtual, which will allow subclasses for time varying constraints.
//
