Moving commentMap and keyToRecordIndex, and adding comments for them
Fixed some broken parts of the last commit, including missing return statements and broken deletes.
First attempt at optimistic updates, with no failure mode
First attempt at using dataSource for all XHRs, though it is not responding to errors properly
Adding failure callback, but struggling with optimistic creates
Another attempt at optimistic comments by changing commentMap to key by row key
Only create a comment element when a row is selected
Fix a bug with paging comments, as we need our record indexes incremented
