Standing surface pools

- hydrology.surfacePools defines bowls filled with their own fluid; riverPolicy.surfacePools opts areas in
- Pools are independent SURFACE_POOL courses with one STANDING_POOL segment, shaped by the erosion field, kept clear of rivers and off slopes
- Locators accept the pool selector and pool ids; validator, renderer, probes and docs follow
