 File defining the `EffAndError` class. The class contains of three memebers; value, upper error and lower error. It is used to save efficiencies in [[Efficiency.cpp|Efficiency.cpp]]. It was originially thought we will have to calculate the efficiency errors properly, however, turns out we don't. But if someone wants to, they hapilly can my simply modifying the functions in this file.
