Config bjet hypo from chain dict

This MR adds function to configure hypo tool directly from the chain dict. There is one small change I had to make in c++. The MonTool is now a private one. Helps in self-testing and is future proof ... when we do not have public tools anymore. Also added an entry in CMakeList that makes nice self-test that was there runable by just ctest command. Tagging @fpastore and @cvarni
