Reconciliation challenges (full version)

Reconciling two columns is easy if:
- totals are the same
- numbers are not grouped differently on the two sides
- numbers are grouped differently but have consistent labels so you can group them
It's doable (but can be slow) if
- numbers are grouped differently, but have labels which a human can match up
Without Sotozeo, it's difficult to very difficult if
- numbers are grouped differently and labels are irrelevant, inaccurate, or incomplete.
With Sotozeo, all of these cases are easy.
