/// Definition of atoms.
/// Only the basic information: name, notation, atomic weight and charge.
///
/// The principle of definitions of atoms is dictionary or a database:
/// the atoms are not repeated,
/// each atom is presented in the total system no more than one time.
/// The system knows each atom presented in it.
/// The atom 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 atom,
/// it has to use either char* (string) notation, or pointer (or reference)
/// to one of these objects.
/// The user pogram can initialize the new atoms.
/// The standard atoms are initiated in files GasLib.h and GasLib.c.
///
/// In principle I am going to initiate all atoms from Mendeleev's table,
/// but I haven't finished yet. Only its first half is filled at the moment.
///
/// The atoms are registered in the static element of class AtomDef
/// private:
///   static std::list<AtomDef*> logbook;
/// The can be obtained by notations by:
/// public:
///   static const std::list<AtomDef*>& get_AtomDefLogbook();
///   static AtomDef* get_AtomDef(const std::string& fnotation);
///  returns the address of atom with this name if it is registered in system,
/// or NULL otherwise.
///
/// In these files and in the other components of the matter package
/// the principles are similar. This is the principle of database, the principle
/// of the strict protection of internal data (variables marked by
/// suffix 'h') and granting access though the functions which have similar
/// names without this suffix 'h'.
