HBookHistogram

HBookHistogram - C++ concrete implementation class for histograms.

The HBookHistogram class is descended from the more general HepHistogram class. It provides a simple and generic interface to the HBook histogramming library.

The code assumes that FORTRAN is callable from C by the (mostly) standard BSD convention: all lowercase symbol names with an "_" appended.
