added: Pattern::CacheFunctions(Functions<StreamType> & fun)

you can cache all functions (their addresses) in the pattern

changed: now we have two methods for generating content:
       Generator<>::Generate(StreamType & o, Pattern & p, Functions<StreamType> & f);
       similar like previous -- Set(...) methods were removed as well as the second ctor 

       and a second one:
       Generate(StreamType & o, Pattern & p);
       without functions, the functions should be cached beforehand in the pattern
       by calling CacheFunctions() method on the pattern
       this gives O(1) complexity when looking for a specific function
       previously was O(log n)
