GammaLib

The context of this task is the extension of the gammalib to allow the analysis of data from Cherenkov telescopes in a way currently adopted by the HESS/VERITAS/MAGIC collaborations: the ON and OFF technique, which can be used in different ways. As a first step, we focus on the spectral analysis of a source observed i wobble mode, with the reflected region background evaluation method (see Berge et al. 2007).

A first step toward this is to implement a class to define regions over the sky. Following some discussion, three class headers have been written:
- An abstract class interface GSkyRegion
- A derived class GSkyRegionCircle for a circular region
- A sky region container GSkyRegions
These are very likely perfectible and the immediate objective is to refine the interface and fill in their functionalities during the coding sprint to be held in Toulouse on 24-28 June 2013.

The philosophy is explained in the comment section of each class header, which also contains a list of points to be clarified/discussed.
