Detailed Description

Mandatory class for the construction of geometry.

This class is used to create the world volume and keep track of some dimensions. World volume is the only one created and saved here, whereas voxels and sensitiveness are accounted for by another class.

Note

Different class will use some information to this class such as geometrical constraints on the simulation world volume.
