Mass refactoring

Some changes:
+ Added support of functions with multiple arguments
+ Added some default function (min, max, avg). just example of multiple arguments :)
- Removed variables support (I think they pointless)
~ All tokens now in individual classes
~ Parsing based on regular expressions
~ Fix negative numbers
~ Fix grouping with brackets
