class FEMComponent
/*
   This class is an abstract class, the superclass of all classes that imple-
   ment the components of a finite element mesh : elements, nodes, time steps,
   materials, loads and load-time functions.
 DESCRIPTION
   This class defines the two attributes common to all component classes ;
   'number' is primarily used for reading data in the data file. 'domain' is
   used for communicating with other components (e.g., for an element to ob-
   tain its material), for accessing the linear system and the data file.
 TASKS
   Reading data in the data file.
