1) Changes to Clusterviewer and it's python script to show different markers for start/end points.
2) Added comments to ana_info_struct to remind me what the different variables mean
3) Initial additions to KalekoClusAna to check for angle matches and start/end point matches between 2D clusters... only for u-clusters right now, for debugging
4) Added a run script macro that adds viewer + kalekoclusana as modules to do both simultaneously.
