The PED spectroscopy by the matrix inversion algorithm is now
included.
This commit also includes:
* some changes in default values in parameters.py for eigval_ipwm, eigval_method
in SpecParameters and phi in SourceParameters
* a modification in the cluster viewer: the mouse wheel allows to change the
transparency and see the emitter
* in utils.py, the hemispherical_cluster function has a new keyword that allows
to create cylindrical clusters
It was impossible to perform an energy scan in EIG spectroscopy.
The calculator and calcio modules were corrected.
We can now compute the spectral radius vs energy with and without
renormalization for EIG spectroscopy mode
The G_n, Sigma_n, Z_n and Lowdin K^2 methods are supported for
the inversion algorithm.
This commit fixes also several issues in the GUI and in the
hemispherical_cluster function
