Numeric expression evaluations

==Overview of Numeric Expression Evaluation==

Numeric expression evaluation is represented by '''TNumber''' class with several constructors for any kind of type you want to work with: Double ('''TDouble'''), Fraction ('''TFraction'''), Complex number ('''TComplex'''), Matrix ('''TMatrix'''), Algebraic system ('''TSystem''') or number with infinities ('''TInfinity'''  - obsolete one - will be merged with '''TFraction''' later).
