The projection handler is a central repository for histograms (and other analysis stats objects) to be used in a Rivet analysis run. This eliminates the need for analysis classes to contain large numbers of histogram pointer members, and allows histograms to be accessed via more user-friendly names than C++ variable names allow.

The projection handler is a central repository for histograms (and other analysis stats objects) to be used in a Rivet analysis run. This eliminates the need for analysis classes to contain large numbers of histogram pointer members, and allows histograms to be accessed via more user-friendly names than C++ variable names allow.
The core of the HistoHandler design is that it is a singleton class, essentially a wrapper around a map of AnalysisObject*, indexed by a hash of the registering object and its local name for the registered projection.

Histo clearing method: deletes all known histos and empties the reference collections.
