     A multigraph is a graph where edges between nodes can be
     represented several times. For some algorithms this causes
     problems. 'duplicatedEdges' tests an instance of the 'graphNEL'
     class to see if it has duplicated edges and returns 'TRUE' if it
     does and 'FALSE' otherwise.

     It would be nice to handle other types of graphs.

_V_a_l_u_e:

     A logical, either 'TRUE' if the graph has duplicated edges or
     'FALSE' it not.
