Return a string containing the type of the given branch.

Works both with real TTree branches and with temporary column created by Define. Throws if type name deduction fails. Note that for fixed- or variable-sized c-style arrays the returned type name will be RVec<T>. vector2rvec specifies whether typename 'std::vector<T>' should be converted to 'RVec<T>' or returned as is customColID is only used if isCustomColumn is true, and must correspond to the custom column's unique identifier returned by its GetID() method.
