Allow the preprocessor to cache the lexed tokens, so that we can do efficient lookahead and backtracking.
1) New public methods added:
-EnableBacktrackAtThisPos
-DisableBacktrack
-Backtrack
-isBacktrackEnabled
2) LookAhead() implementation is replaced with a more efficient one.
3) LookNext() is removed.
