 * DESCRIPTION:  
 *   Serial HEAT2D Example - C Version
 *   This example is based on a simplified 
 *   two-dimensional heat equation domain decomposition.  The initial 
 *   temperature is computed to be high in the middle of the domain and 
 *   zero at the boundaries.  The boundaries are held at zero throughout 
 *   the simulation.  During the time-stepping, an array containing two 
 *   domains is used; these domains alternate between old data and new data.
 *
 *  The physical region, and the boundary conditions, are suggested
    by this diagram;

                   u = 0
             +------------------+
             |                  |
    u = 100  |                  | u = 100
             |                  |
             +------------------+
                   u = 100

Interrior point :
  u[Central] = (1/4) * ( u[North] + u[South] + u[East] + u[West] )
