Detailed Description

Class to Wrap a ROOT Function class (like TF1) in a IParamFunction interface of one dimensions to be used in the ROOT::Math numerical algorithms The parameter are stored in the WrappedFunction so we don't rely on the TF1 state values.

This allows for the copy of the wrapper function without the need to copy the TF1. The wrapper does not own the TF1 pointer, so it assumes it exists during the wrapper lifetime
