Detailed Description

Spin sorted pi0 histograms.

Author

Jason C. Webb Class to contain spin-sorted pi0 histograms for analysis. We inhereit from TDirectory, and store all histograms w/in. The directory should be inserted into the owning maker's .histos directory. Each instance of this class is meant to store histograms for one spin state.
