/*
 *  Name:           closeFiles
 *  Input:          input FILE pointer
 *                  output FILE pointer
 *                  metric FILE pointer
 *  Output:         none
 *  Return:         void
 *  Description:    Routine closes the three files used during application.  
 *                  The return values for the system call to close the files 
 *                  are checked but not acted upon.  Any error occuring during 
 *                  the closing of the files is non-fatal, since the routine is 
 *                  part of the Input & Output module exit process.  
 *                  Appropriate messages are placed in the error message buffer 
 *                  whenever an error does occur.
 *  Calls:          errorMessage()
 *      System:     assert()
 *                  fclose()
