HELP SECTION

usage:        GraphModel[elemat_,npe_,nel_,scl_]
    elemat_      is the FEM element matrix
    npe_        is the number of nodes per FEM element
    nel_        is the number of FEM elements
    scl_        is a three element list for view of object                   

example:    GraphModel[elemat,npe,nel,{1,2,1}];
or:
    elemat     =    {{{0,1,1,0,0,1,1,0},{0,0,1,1,0,0,1,1},{0,0,0,0,1,1,1,1}}}
    npe        =    8
    nel        =    1
    scl        =    {1,2,1}
