Detailed Description

Definition of particles. Only the basic information: the name, the notation, the mass, the charge, and other auxiliary data.

The organization is similar to AtomDef from directory matter, with the exception that the internal data are not declared as private. Of course, the user should not change them.

The principle of definitions of particles is dictionary or a database: the particles are not repeated, each particle is presented in the total system no more than one time. The system knows each particle presented in it. The particle characteristics can be obtained by literal notation. The system declines the secondary initialization. The copying is not declined. When the user program wants to refer to particle, it has to use either char* (string) notation, or pointer (or reference) to one of these objects. The user pogram can initialize the new particles. The standard particles are initialized right here, below.
