  Reafactored Lexer class to allow chaining. The full chain when parsing #if directive looks like this: Preprocessor -> MacroExpander -> DirectiveHandler -> MacroExpander -> DefinedFilter -> Tokenizer. This chain dynamically changes depending on the current context.
  
  Also added an incomplete implementation of #if handling and ExpressionParser to illustrate how this design is supposed to work.
