0005  * BTagCalibration
0006  *
0007  * The 'hierarchy' of stored information is this:
0008  * - by tagger (BTagCalibration)
0009  *   - by operating point or reshape bin
0010  *     - by jet parton flavor
0011  *       - by type of measurement
0012  *         - by systematic
0013  *           - by eta bin
0014  *             - as 1D-function dependent of pt or discriminant
