1)Implement another declaration of 'Token::eraseTokens' with parameters: the starting token and the number of times needed to call 'deleteNext'.
2)Use the overloaded 'eraseTokens' where needed instead of using consecutively 'deleteNext'. 3)Tokenizer: general optimizations about the deletion of some tokens. 4)Run astyle.
