Description
Get all indices from catalog
Compute all "good" combinations of indices (really a power set but heuristics)
For each batch of indices (received in goodness order in batches):
1. Logical rewrite (noop for now)
2. Covering analysis
3. Sort analysis
4. If possible, ship
If no indices shipped, output collscan.
