def automaticSurveySelection(self):

        Option for automatic selection of surveys among the raw data set.

        Algo:
        A time threshold is asked to the user, and used as a criteria to 
        separate different survey. Time intervals between measurement dates for
        which station number changes are compared to the threshold. 
        If it is higher, a new survey is considered.

        The base station is asked to the user

        Remarks:
        Only works when the base station (asked to the user) is allways the 
        same. Whether the base station number is the same as the cycling
        station number is asked to the user.
        when complicated loop geometries are used, or for specific survey 
        designs, this option is likely to fail.
