// Purpose: This file contains the class interface for Node.
// A Node provides the abstraction for a node in the FEM.
// Nodes have original position, trial displacement, velocity and 
// acceleration and committed displacement, velocity and acceleration 
// (the last committed() trial quantities).
//
