Detailed Description

template<class T>
class HistSparse1D< T >

Sparse 1D histogram based on a map.

Simple implementation for what we need. ROOT's THnSparse is really complicated and couldn't get to work - overly complex for what we need. Boost histograms are better but we don't have a dependency on that yet, so for now a super simple one of our own.

This doesn't have any limits and just accumulates for each unique key forming a set of keys.
