Detailed Description

template<class T>
class scaleFunctionBase< T >

The correct functor is selected at job start in the constructor. The pt value is taken by reference and modified internally. eta, phi and chg are taken by const reference.
Made into a template so that it can be used with arrays too (parval for the scale fit is an array, because Lykelihood is an extern C function, because TMinuit asks it).
Note that in the array case it takes the pointer by const reference, thus the elements of the array are modifiable.
