Detailed Description

A derived class of ProjectorBase that projects data accumulated by calls to its fill function into a one dimensional histogram.

A vector of ProjValue1D objects is created and presented to a client via an iterator. The binning parameters are fixed hence it is called static 1D histogram-mer.
