* Here is the documentation of the LWHFactory class. It inherits from
* the abstract FactoryBase class and implements the Light-Weight
* Histogram package, LWH. This implements the most rudimentary
* histogramming facilities according to the <a
* href="http://aida.freehep.org">AIDA</a> interface
* specifications. Currently the only thing that is supported is
* simple, equally binned, one dimensional histograms. It is mainly
* intended to be used in applications where one needs to fill simple
* histograms and output them. With LWH it is then possible to do this
* without the overhead of a full AIDA implementation, but still
* having the option to use a full implementation later on with
* minimal changes.
*
