Konstancja Satalecka / ctools

Filenames are now always accessed using the filename() method so that environment variables get correctly expanded.

The prefix is now accessed using the string() method instead of the generic value() method, so that string checkings can be performed.

In case that the observation container holds more than a single observation, ctobssim now outputs an observation definition XML file in addition to the event files. The filenames of the event files will be stored in the observation definition XML file so that subsequent ctools can handle all observational data together.

…and GCTAModelRadialAcceptance::mc method.

Instead of using the m_deadc member we use now the GObservation::deadc method to access the deadtime correction factor.

The deadtime is controlled using the deadc parameter. An additional MC process decides whether a photon event or a background event falls within a dead period of the system or not.
