Making progress

Just an update on the progress ("are working" == unit test I can find for the operations are successful).

• Documents are working
• Transactions are working
• Queues are working
• Mapped indexes are working

The only things that seem to remain as far as full functionality are the map->reduce working set tables, the tasks tables and the attachment tables.

There's nothing much to report as far as anything interesting.  All of the extra operations involved are basically just copies of the existing access methods.
