Added two new Heuristics (GreedySearchNoConf and RoundRobinNoConf) both
not self avoising and with both could solve the system for 7 cases in
around 64000 evaluated nodes. Additional I added a system that uses the
symmetrie in the system by sorting the new arrays instead of addings
logical copies of each other. Problems with the full system are still
there and could only be solved by solving the array mass problem. But
this should be possible by limiting the size of the arrays to that what
is necessary, but this would force a reimplementation of nearly all
code.
