#17 ability to run 'rube generation' offline

[Alan Matthews]

currently, the 'orb' program must be called to create
the rube. there needs to be a way to run the same
algorithm off-line; unattended at night for example.

it might be striaghtforward to just output the SQL
statements to a file, but that might not take into
effect a change in data; for example, an addition of
data that pushes certain dimension values over the 'row
limit' value.

however, as an expedient solution, that might work. a
separate program to run this offline might work, or a
way to run the java-swing orb 'unattended' might also
be a workable solution.
