TODO:
* This should open the metadata dictionary if available or create it
* it should create or give access to the photon histograms
* it should provide an interface whereby cross channel correlations 
  on the raw data can be executed
* it should supply filters for the meta data to allow the correct 
  selection of files and/or photon histograms
* This should create & save histograms:
    * ADC values
    * Photon counts
    * ....
