Detailed Description

Represents the most simple particles such as Electron, Muon, Photon, etc.

the motivation being that all particles are the same type from the point of view of kinematic state variables, and are only differentiated by having a different "label".
It implements an "IKinematic" interface which is designed to standardise kimematic attribute query method names.
