/**
* \brief DirectoryHelper
* \details this class is designed to help mitigate some of the commonly performed
* operations on directories. namely:
* 1) the ability to determine the number of series in a directory by what type
* of series is present
* 2) the ability to find all ct series in a directory
* 3) the ability to find all mr series in a directory
* 4) to load a set of DataSets from a series that's already been sorted by the
* IPP sorter
* 5) For rtstruct stuff, you need to know the sopinstanceuid of each z plane,
* so there's a retrieval function for that
* 6) then a few other functions for rtstruct writeouts
