0006  * BTagEntry
0007  *
0008  * Represents one pt- or discriminator-dependent calibration function.
0009  *
0010  * measurement_type:    e.g. comb, ttbar, di-mu, boosted, ...
0011  * sys_type:            e.g. central, plus, minus, plus_JEC, plus_JER, ...
0012  *
0013  * Everything is converted into a function, as it is easiest to store it in a
0014  * txt or json file.
