9/// Definition of a gas.
10/// haracteristic feature of the Gas class is that it consists of molecules.
11/// Additional feature is that the density can be calculated by temperature
12/// and pressure. But this is not always, and therefore it is not characteristic
13/// feature. Then with only one this feature (consisting of molecules)
14/// we can describe as gas also some other substances, for example, the liquids.
15///
16/// Only the basic information: the data of matter, plus the pressure.
17/// Note that the class AtomMixDef undirectly appear twice.
18/// It is the base class of matter and molecula. Therefore it is
19/// indirectly the base class of GasDef, and the base class
20/// of its external elements - DynLinArr< PassivePtr<MoleculeDef> >molech.
21///
22/// As the base class of GasDef, the class AtomMixDef determines only the
23/// relative weights of atoms of different sorts. Also note that
24/// the atoms of the same sorts participated in different molecules,
25/// included in AtomMixDef as different atoms.
26///
27/// As the base class of MoleculeDef, the class AtomMixDef determines
28/// also only the relative weights of atoms of different sorts in the given
29/// molecule, since the class AtomMixDef doesn't have space to encapsulate
30/// the number of atoms. But the latter number is also necessary: consider H2,
31/// the relative weight of H is 1, and nothing says that there are two atoms.
32/// Therefore in the class MoleculeDef there is additional array, which
33/// gives the numbers of atoms of each sort, and also there is another
34/// parameter giving the total number of atoms in molecule.
35///
