Detailed Description

Generates a lightcurve

The cslightcrv class generates a light curve for Imaging Air Cherenkov
Telescope event data by performing a maximum likelihood fit using
ctlike in a series of time bins. The time bins can be either
specified in an ASCII file, as an interval divided into equally
sized time bins, or can be taken from the Good Time Intervals of the
observation(s).

The format of the ASCII file is one row per time bin, each specifying
the start of stop value of the bin, separated by a whitespace. The
times are given in Modified Julian Days (MJD). 

Examples:
        >>> lcrv = cslightcrv()
        >>> lcrv.run()
        >>> ... (querying for parameters) ...
        >>> fits = lcrv.lightcurve()
            Generates a light curve and retrieves the results in
            a FITS file.

        >>> lcrv = cslightcrv()
        >>> lcrv.execute()
        >>> ... (querying for parameters) ...
            Generates a light curve and saves results in a FITS file.

        >>> lcrv = cslightcrv(obs)
        >>> lcrv.execute()
        >>> ... (querying for parameters) ...
            Generates a light curve from the observations in an
            observation container and saves results in a FITS file.
