Catrope d9cd1392fc Add TransactionProcessor tests, and fix TP to make them pass
* Add .process() and its helpers from ve1

** Use data[i] rather than data[j]
** Don't add empty annotation objects for no reason
** Remove empty annotation objects
*** I thought this wasn't needed, but it is needed for clean rollbacks
* Remove unused second parameter in applyAnnotations() call
