This change adds structures for saving TokenLocations in the Storage and improves the location derival in the ASTVisitor: * TokenLocation saves an Id of a Token. For each Token two TokenLocations are created for both start- and endpoint. They keep a reference to each other and know whether they are start or end. * TokenLocationLine saves all TokenLocations in a line and the lineNumber. * TokenLocationFile saves all TokenLocationLines of a specific file and the filePath. * TokenLocationCollection saves multiple TokenLocationFiles. * TokenLocation can derive it's lineNumber and filePath through references to first TokenLocationLine and from there to TokenLocationFile.
