For the first portion of the rewrite, I will focus on getting a basic
journal/ledger structure up on fully rewritten code.  This will include
basic financial statements, batches, vouchers, journal entries, etc.

I expect to start on this in 2-3 weeks.  Below is a draft of what I hope to
accomplish.  The scope of this part is just general ledger/general
journal-related functionality.

I  Strategic Requirements

Very old data may be purged without affecting reports outside that period.
 Companies can set their own retention policies.  We do not need to provide
a user interface immediately for such purging though.  Access to this
should be through the standard financial interface with additional options
selected.

Within the retention period, all state transitions for financial
transactions must be auditable.  This includes deleting and updating drafts
and vouchers.

We need to support faster locking and lock unlocking for discretionary
locks.

II:  Journal Entry Specifics

Journal entries must balance to be entered into the books.
Journal entries do not cross dates
Journal entries may not be marked deleted after being approved
Journal entries may exist as templates, drafts, vouchers, or approved
transactions
Approved transactions may be reversed.
Drafts, templates, and vouchers may be non-destructively "deleted"
Deleted templates may be purged.

III:  Reports for this phase include:

General Ledger and Transaction Search
Current Balances/Chart of Accounts
Trial Balance
Income Statement
Balance Sheet

These reports must be able to tolerate purged data and be tested with
purged data.

The general ledger and transaction search report must have options to show
templates and deleted transactions, as well as individual vouchers and
drafts.

Draft and batch approval will go through this report.

IV:  Transaction Approval:

Draft approval will go through gl and transaction search
Batch approval will have an additional listing that will click through to
the general transaction search.

The stage after this will be basic ar/ap without inventory.
