extensive changes to accomodate 1x1 binning of the HighRes? detector. It is implemented as a global flag. Currently only 4x4 and 1x1 are allowed. 1x1 has never been tested in reality, only simulated data - so my assumed dimensions may not be correct. look for TODOHIGHRES in the file for places that may need to be updated for different file dimensions. Testing of the simulated data is proving to be excruciatingly slow, but passable for a test. Speed optimization will be needed if this is the final solution. Memory management will also be an issue since every "copy" of the highRes matrix is enormous. Carry as few of these around as possible in the future to keep the experiment size to something reasonable.

+// data collected after 10/3/18 should not need this patch since the
