\subsection{Detailed Description}
This class represents the Gamma distribution. 

It supports training a Gamma distribution on a given dataset and accessing the fitted alpha and beta parameters.

This class supports multidimensional Gamma distributions; however, it is assumed that each dimension is independent; therefore, a multidimensional Gamma distribution here may be seen as a set of independent single-\/dimensional Gamma distributions---and the parameters are estimated under this assumption.

The estimation algorithm used can be found in the following paper\+:
