...in preparation for concurrent processing of documents. Parsing and reparsing is handled by TranslationUnit. Since we will do this in a different thread, extract the core logic into the new class TranslationUnitUpdater, so that we can prepare the necessary data for the run and then later incorporate the results of the parse/reparse.
