Parametrization class
=====================

Parametrization class link the (possibly filtered) density parameter to the
simulation material propertie. 
Each parametrization requires the parametrized material property name such as 
defined in the solver IO shield.
A helper plot function also allow visualizing the transformation of the density
parameter to material properties. See the end of the page.
