#5248: edge_colors does not work on loops
--------------------------+-------------------------------------------------
 Reporter:  mhampton      |       Owner:  rlm       
     Type:  defect        |      Status:  new       
 Priority:  major         |   Milestone:  sage-3.4.1
Component:  graph theory  |    Keywords:  graphs    
--------------------------+-------------------------------------------------
 The following example illustrates the problem.  Loops are treated
 seperately, and not correctly colored (they are always black).

 {{{
 g = graphs.CompleteGraph(3)
 g.loops(True)
 g.add_edge(0,0)
 c_dict = {"red":[(0,0)], "blue":[(0,1),(1,2),(0,2)]}
 show(g.plot(edge_colors = c_dict))
 }}}
