Description
Part of the Union components, a set of components that work together and thus
sperates geometry and physics within McXtrace.
The use of this component requires other components to be used.
1) One specifies a number of processes using process components
2) These are gathered into material definitions using Union_make_material
3) Geometries are placed using Union_box/cylinder/sphere, assigned a material
4) This master component placed after all of the above
Only in step 4 will any simulation happen, and per default all geometries
defined before this master, but after the previous will be simulated here.
There is a dedicated manual available for the Union_components
