Changes in the public API
The syntax of the OHAxis class, which is a helper class for publishing raw histograms, has been changed. It's not a template class any more, but it has 2 template constructors instead:
template
OHAxis( const std::string & label, size_t bincount, T low, T width );
template
OHAxis( const std::string & label, size_t bincount, T * bins );
