Normal classes:

HistogramC	Histogram with discrete bins.
RealHistogram1dC	Create a histogram of real values.
RealHistogram2dC	Create a histogram of real values.

Normal functions:

operator <<(ostream &,const RealHistogram1dC &)	Write to stream.
operator >>(istream &,RealHistogram1dC &)	Read from stream.
operator <<(BinOStreamC &,const RealHistogram1dC &)	Binary stream IO.
operator <<(BinIStreamC &,RealHistogram1dC &)	Binary stream IO.
operator <<(ostream &,const RealHistogram2dC &)	Write to stream.
operator >>(istream &,RealHistogram2dC &)	Read from stream.
operator <<(BinOStreamC &,const RealHistogram2dC &)	Binary stream IO.
operator <<(BinIStreamC &,RealHistogram2dC &)	Binary stream IO.
