…_logic() methods. (Following circle region implementation, extended). Extended test_GSkyRegions_io() and test_GSkyRegionMap_logic() methods. Obviously lots of tabs have been automatically replaced by spaces.

…se dist/posang). In terms of that, sorted out previous issues towards the poles. No longer need precomputed sin/cos, hence removed cache. Added 1e-10 tolerance for skydir containment check. Changed corners indexing, now starting with +RA+DEC and counting CCW. Improved documentation.

…ect centre and their cartesian representation (previous implementation used difference in RA/DEC)

…rs (method GSkyRegionCircle::contains(GSkyRegion))

…ng now use of the new PA.

…lemented a cludge for computing the overlap of rectangle-rectangle.

…ethod contains_local(GSkyDir). Implemented contains(GSkyRegion) for rectangle.

… (ds9 line) and written to ds9 string. Can be set via radians and degrees, the latter is implemented for the constructor. Changed solid angle computation algorithm.

The GCTAModelIrfBackground::eval() method uses now the GCTABackground3D::rate_ebin() integrator method instead of the GCTABackground3D::operator() operator so that the background model evaluation is no longer sensitive to the number of energy bins.

The GCTACubeBackground::fill() method was simplified, removing the power law integration which was not accurate enough, and using directly the GCTAModelIrfBackground::eval() method which is now exact.
