class to generate the Helas calls for a FKSProcess. Contains: -- born
ME -- list of FKSHelasRealProcesses -- color links -- charges -- extra
MEs used as counterterms

**opts)
constructor, starts from a FKSProcess, sets reals and color links. |

set_color_links(self)
this function computes and returns the color links, it should be
called after the initialization and the setting of the color basis |
