Rewriter works the next way: you visit AST nodes which are interesting for you,
take their SourceRanges's, and use Rewriter methods like ReplaceText or
RemoveText to replace _text_, corresponding to the node, with your _text_,
or remove it, respectively.

So, you change not AST nodes but replace strings inside source whith other strings.
