This is how they do it on the web, really. It works as expected and matches any flavor of newline (Win, Unix, Mac) despite the ambiguity that "\n\r" can be matched by two subrules, in the end it will be properly matched just by one rule. Also, grammar can be k=2 for lexer.

For example, it can now be used in Conditional, which is done as well.

Introducing base abstract class FunctionalOperator and template Operator<T> for a functional operator returning given type of Value. Assortment of copy methods and apply methods.

Intended as a base class for library-user-level operators and rules. Allows manipulation of Variables via get, set. Intoduces cloning support.

Doesn't hurt and can help.

Some other refactoring too, some augmented comments etc.
