Symbolic expression evaluations

==Overview of Symbolic Expression Evaluations==

Full symbolic expression can be stored in '''MItem''' Class. You can operate with instances of this class using standard operators + - * / and it has several methods to make it easy to operate with expressions. Actually, '''MItem''' is very interesting class that was fully designed by Andrey and it has not been used anywhere before. For example: it doesn't support - and / operators at all (meaning it cannot store and work with them), instead of it every part of '''MItem'''  Class expression has Boolean fields: '''Negative''' (means -a) and '''Inverse'''  (means 1/a). So, you should respect this fact in order to avoid some errors.
