TestFittingModule switched to new FitSuite, Observer pattern and new FittingHelper to follow fit iterations

Bug fix in OutputData from ASCII file, TestMesoCrystal moved in TestMesoCrystal1, TestMesoCrystal2 now for fit purposes, bug fix in MultiLayerRoughnessDWBA calculations (m_alpha_i -> -m_alpha_i)

Protection against positional options arguments (without '--'). New GISASFW_JCNS environment variable.

Added enhancements for mesocrystal form factor and spherical particles with Gaussian distributed radius

Fixed issues with complex Bessel function in cylinder form factor + corrected normalization of Gaussian and Lorentzian form factors

Evaluate form factors for complex wave vectors (1): provide interface and implemented it for part of the Formfactors

Implement multiparameter fitting (3): added necessary normalization to enable comparison with experiments: added volume factor for reciprocal lattice vectors
+ refactored formfactor decorators

Export of OutputData in python; isgisaxs9 and mesocrystal functional test are exported to python, many corresponding changes.

OpticalFresnel now without static, new PythonAPI directory and automatic make, make install from Macros/BoostPythonGenerator
