Evidence based approach

Start with the ebay expenses table, then iteratively find evidence in
the flow table.  Evidence is is the minimal match of amount + date

Hmm... going crazy again.

The simplest approach seems to be to add a human-readable annotation
to each transaction id.  Something that is enough to cross-ref with
other tables.  Don't bother with id?

So let's just use temporary tables.
Create a copy of a usable view and edit it.  Then copy into mapping table.
