Renamed tag for PyPI

• Need a new filename.

Fix versioneer installation

• PyPI installations were failing to find the versioneer module.

Package renamed to CFcal

• To avoid a name clash on the PyPI server, the package has been renamed 'CFcal'

Add support for versioneer

• The version number, cflib.version, specifies the release tag and, if applicable, the commit hash of the Github repository used in building the package.

Support for more CF lineshapes

• This version allows calls to the spectrum and NXspectrum functions to specify both sigma and gamma values. If only sigma (gamma) is given, the crystal field line shape is gaussian (lorentzian). If both values are given, a pseudo-voigt line shape is used, as defined in Ida, Ando and Toraya, J. Appl. Cryst. 33, 1311 (2000).
