        - Display a file opening window
        - Populate a Campaign object: read all raw data
        - Set a new window for survey selection options
        - link selection options to apropriate functions:
          3 options are currently available: an automatic selection, a
          a selection with a user input file containing start-end dates for
          each survey, and a single srvey selection with a single start-end
          date 
          Each option calls the appropriate function:
              automaticSurveySelection()
              load_start_end_dates()
              askUserSingleSurvey()              
        which then calls the generic self.baseStationSelection() function
        which eventually calls the data populating methods within the 
        data_objects module with the appropriate options.
