The CTA response was refactored. GCTAResponse was renamed GCTAResponseIrf, and GCTAResponse became an abstract base class for all possible CTA response functions. GCTAResponseIrf derives from GCTAResponse. Also GCTAResponseCube derives from GCTAResponse.

To make this work, the GObservation::response() method now returns a pointer instead of a reference. The interface definition is such that the pointer never can be NULL. The code has been adapted to comply to this new interface.

Upon reading an XML file, GCTAObservation now determines the appropriate reponse type and calls its reader. If no response is specified in the XML file, GCTAResponseIrf will be used by default.

Adapt the code to the usage of GCaldb for response access.

The coding and design conventions (CDC) document was also updated.

The GCOMPointing class is now obsolete as no GPointing class is required anymore. The pointing can now simply be stored in a GSkyDir object.

The GFits class now derives from GContainer and implements all generic container class methods (at(), size(), isempty(), set(), append(), insert(), remove(), reserve(), extend()). The hashdu() method has been renamed to contains() for compliance with other container classes. The hdu() methods have been renamed to at(), also for compliance. Boolean arguments are now passed as const references, and members are returned as const references. HDU access operators[] have been implemented to access FITS extensions without range checking.

After renaming GWcs to GSkyProjection the code has been adapted to the new naming convention.

Add GChatter argument to print() method.

The print() method now takes an argument of type GChatter to control the chattiness of the output in a homogenous manner.
Pass NORMAL chatter level in __str__ method.
Add chatter argument to print() methods.
Use GLog::chatter() method to control the chattiness of the log stream operator.
Add chatter() methods and provide member access through const references.
Add chatter() methods, provide member access through const references, and declare one liners as inline methods.

The chatter() methods control the new m_chatter attribute that is used to control the chattiness of the object's print() methods.
name() and version() methods return const references.
logFileOpen() method now sets the chattiness from the applications's chatter parameter, and name() and version() methods now return a const reference.

The IAQ parameter allows specifying a response file for each observation.

All data space cubes that are defined in Mercator's projection are automatically transformed into cartesian projections. This kluge is necessary to correctly exploit the COMPTEL data files available from the HEASARC web site. The kluge only operations on Mercator's projections and leaves all other projections inaffected. This means that if the WCS definition of the COMPTEL data were corrected, the code should also handle these files correctly.

DRE file attributes are now correctly read, and the deadtime is fixed to 15%. A kluge has been added to digest the corrupt GSFC files (their WCS definiton is incorrect).

Initial methods for handling DRB, DRG and DRX files have been implemented, yet no testing is performed so far to verify that the dimensions are compatible.

This initial version correctly reads the DRE file.
