Detailed Description

Class to get randomly cascades (with lateral feeding) of gammas on the basis of a level scheme.

With BaseGEM, cascades are determined randomly in a level scheme. The produced cascade ends with the first populated link (level) which is the entry point in the level scheme. It should be enought for some experiment (beta decay experiment), but in several cases (fusion-evaporation), the lateral feeding produces gamma-rays which can be also simulated by many different models.

This class is designed to help in this kind of situation. After the BaseGEM random process, it calls the feeding process which is just a particular Link which has its own DoCascade member.
To set the feedink link, use the SetFeeding member. Unless removed, the link belongs to GEM and will be deleted in the destructor. In the demos directory, there is an exemple of how to write a feeding link (see TestFeeding).

Todo:: initialisation with a existing level scheme by copying it (copy constructor for level scheme)
