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)
