Constructor.

Arguments:
name    -- String for the name of the resulting histogram
mapping -- Dictionary for mapping the bin label to a histogram name

Keyword arguments:
normalizeTo -- Optional string for a histogram. If given, all bins of the resulting histograqm are divided by the integral of this histogram.
