Detailed Description

Make a weighted random selection of an element.

This selects an elemental component (atom) of a material based on the precalculated cross section CDF tables of the elements in the material. Unlike ElementSelector which calculates the microscopic cross sections on the fly, this interpolates the values using tabulated CDF grids.
