very strange problem in 2.4

Ok, so I found out that even though mylist[] and all objects in it were
fine ie id(mylist[i]) != id(mylist[all others]) what was happening is
that during a reproduction function a shallow copies were being made
making all offspring (genetic algorithm) have different
id(mylist[0..n]), however the actual attributes were referenced for
offspring on the same parent(s).  Fixed it with a deepcopy and used
properties insead of java like get sets.

thanks for all the help,
Conor
