Pythonize the TTree::SetBranchAddress method to be able to pass as parameter the reference to the Python proxy object, in particular when calling the (const char*, void*) overload. This helps in cases when the C++ implementation of SetBranchAddress expects the address of a pointer, e.g. when the branch is an std::vector.

Webles that are stored in the form of a TTree. The idea of a TTree is that each event, corresponding to an interaction of interest, is independent from all other events. For example, there is no correlation between what happens in two subsequent beam crossings at the LHC. However, every event should have a given set of information that describes it.
