Detailed Description

base class for managing the spatial part of Cmomentum (defined after)

This class contains the information for particle or group of particles management. It is adapted to use spherical geometry, where, for our purposes, the only time-consuming operation we need is the computation of the norm. To compute it once-and-for-all and store it in a local variable, you should call the 'build_norm' method. On top of that, the angle phi is computed from the x-axis and theta from the "north pole".
