> Currently, the delete algorithm works by immediately performing the deletes 
> and property updates that are required.  While this works, it is not very 
> robust.  If there are errors found during the processing, we need to rely on 
> Titan properly rolling back the transaction.  Given that titan does not 
> guarantee that the transactions are strictly ACID compliant, this may not 
> always be a safe thing to do.  This task changes the algorithm to accumulate 
> the changes to be applied in a DeleteContext and only apply them once all of 
> the processing has been done.  This will make the delete operation more 
> robust.  In addition, it increases the chance that Titan (or whatever 
> underlying graph database gets used (see ATLAS-610)) can batch the updates 
> and perform them more efficiently (and within a single atomic transaction).
