Added "GModelSpectralSmoothBrokenPlaw.hpp" to "GammaLib.hpp"

GModelSpectralSmoothBrokenPlaw.hpp:
- Added the 'pivot' parameter and relevant methods.
- Added cache parameters for various values to aid in the computation of parameter gradients.

GModelSpectralSmoothBrokenPlaw.cpp:
- Added 'pivot energy' to model definitions.
- Updated documentation text.
- Updated '::eval()' method and gradient computations (still need to add gradient formulae for 'pivot', 'breakenergy', and 'beta', next commit)

The GModelTemporalFunc implements a temporal file function for the simulation of transient sources.

The GFft class implements a one-dimensional Fast Fourier transformation. The GFftWavetable class is a support class for GFft and holds the trigonometric coefficients for a factorisation.

An initial implementation of the GNdarray class has been added that implements a n-dimensional double precision floating point array.

… including docs and unit tests

  - New naming scheme.
  - New utility functions/constructor supporting cutoff-energy.
  - Usage of new helper functions for xml read-in/write-out.

Added GWcsSIN class.

The GModelSpatialRadialProfile class is the base class for an arbitrary radial model. The GModelSpatialRadialProfileGauss class basically illustrates its usage, and provides a comparison with the analytical Gaussian model, implemented by GModelSpatialRadialGauss.

The GFilename class handles the decomposition of the filename into the true filename and a FITS extension name.

The bilinear interpolator class holds indices and weights for bilinear interpolation. It has an interpolation operator that operates on a linear array of double precision values.
