// ClassName:    IHistogram1D
//  
// Description:  Definition of the IHistogram1D interface class
//
//               All methods that accept a bin number as an argument will
//               also accept the UNDERFLOW_BIN or OVERFLOW_BIN as the argument,
//               and as a result will give the contents of the resulting
//               UNDERFLOW_BIN or OVERFLOW_BIN bin.
//               The in-range bin indeces are expected to be from 0 to N-1.
//               See also <a href="http://wwwinfo.cern.ch/asd/lhc++/AIDA/">AIDA</a>
