Description : Basic Material Model.
This is the default material model of SPIS.
It is based on a NASCAP-like material models for secondary emission,
photo-emission, and induced conductivity.
Model parameters are the 19 NASCAP properties per material, in order to
be able to use the databases of such material properties.
Some implemtation details may differ from NASCAP, in particular concerning
the distribution function of emitted particles (secondary or photo electrons)
