This process dos nothing and is used for testing
Part of the Union components, a set of components that work together and thus
sperates geometry and physics within McStas.
The use of this component requires other components to be used.
1) One specifies a number of processes using process components like this one
2) These are gathered into material definitions using Union_make_material
3) Geometries are placed using Union_box / Union_cylinder, assigned a material
4) A Union_master component placed after all of the above
Only in step 4 will any simulation happen, and per default all geometries
defined before the master, but after the previous will be simulated here.
There is a dedicated manual available for the Union_components
