|E|2 scaling target
This class implements the target function for calculating the scale factor to normalise to <|E|2> = 1. Note that this is not the same as dividing by <|E|2>, except in a few special cases, e.g. a simple resolution bins calculation. The resulting targen function is the square of the value by which |E| should be multiplied to acheive the correct normalisation.
