This change renames directories in preparation for the great package rename. The repository is now in a broken state because the code itself hasn't been updated. However this should ensure that git correctly preserves history for each file.

-- Credit Balance Data View SQL
|
|
--
|
|
-- This query post-processes RegistrarCreditBalance entities to collapse them
|
|
-- down to one 'true' amount per credit ID and effective time, eliminating any
|
|
-- duplicates by choosing the most recently written balance entry of the set,
|
|
-- and then joins these 'real' balances to the CreditData view.
|
|
--
|
|
-- The result is a list showing how each credit's balance has developed over
|
|
-- time, which can be used to find the actual balance of a given credit at
|
|
-- any particular point in time (e.g. the time when invoices are run).
