A new logic has been implemented concerning the caldb parameter. If the name specified by caldb is a directory, the directory is set as the root directory of the calibration database. The file specified by irf must then be a file provided within this root directory.

If the name is not a directory it is used as the mission name that is used to build the calibration directory path. The irf is then the response name.

The instrument and id attributes provided by an observation were not considering when simulating source and background events. This has been changed now that only events will be simulated when the instrument and id are valid for a given model.

The code

  MANPATH="$man_dir:$(manpath)"

led to problems on opensolaris systems, as $manpath is not defined there. The following code works

  manpath=${manpath:-}
  MANPATH="$man_dir:${manpath}"

The first line sets an empty default value. Note also that the () brackets have been replaced by curly brackets.

Output observation definition files are XML files, hence they should have a .xml suffix to avoid confusion with FITS files.

Fixes #1072.

Before, the following warning was generated:
warning: 'tmpnam' is deprecated: This function is provided for compatibility reasons only. Due to security concerns inherent in the design of tmpnam(3), it is highly recommended that you use mkstemp(3) instead.

The time slice duration is now adapted to the source model flux. The m_max_photons member now defines the maximum number of photons that should be simulated in one slice. This prevents core dumps due to memory allocation problems in case that large fluxes have been specified.

This partially adresses feature #807.

The hidden logfile parameter allows specifying the name of the logfile.

The AIT projection is now available in GammaLib.

…nt projections are proposed in parameter file.

The GCTARoi::contains() method is now used to check for ROI containment.

Background simulations can now be done for any model of type GModelData. This is thanks to the abstract mc() method that has been introduced in GModelData. A test case for the new GCTABackground model has been added to the unit tests.

…g so that also sources outside but at the edge of the ROI will be simulated.

GammaLib is undergoing a major interface change which requires adaption of the ctools code.

This reverts commit 74af6b7c3902e2286d5c2f57a799c5e9e704b742.

This reverts commit 6c5ac97cf36fc45943170964f0377a8abaae5772.

The model access operator of GModels now returns a reference, hence the code has been adapted to accomodate this change.
