Novice mistake: avoids pulling in pip-installed package/module - my bad.

If a list's index equals 0, if not indx returns False - not good! if indx is None is better here. Made multiple changes to ensure consistency.

Taken from the original Ruby unit test, this checks the automated addition of skylight wells in a variant of the US DOE Prototype SmallOffice.
- skylight well roof and 4x surrounding (paired) well walls are successfully generated
- attic floor and adjacent core ceiling below have re-sequenced vertices (accommodating cutouts)
- requested SRR of 5% is achieved
Unfortunately, North & South roof surfaces have not inherited similarly re-sequenced vertices. Their vertices remain unaltered ... TO DO.
Nonetheless, results remain consistent for a cold climate (Quebec), i.e. increases in heating, cooling & fans:
Can't explain the unexpected blip in interior lighting use - the core space/zone does not hold daylighting controls!
Almost there. Back to work ...

That'll do it. A remnant of Ruby's implicit return - my bad.

Both North & South roof surfaces now inherit leader lines and cutouts to accommodate skylight wells. Although roof surfaces inherit such extended vertices (consult generated office_attic.osm file with a text editor), the OpenStudio Application won't necessarily render them - that's OK.
There's now a single eplusout.err file warning on collinear vertices - which is expected. Otherwise, slight (expected) changes in results.
All good for now. More testing to come.

Converting SmallOffice UNCONDITIONED "attic" to an INDIRECTLY-CONDITIONED "plenum" (or similar dead-air space). Greater roof surface areas? Larger skylights + wells (for the same 5% SRR):
Tests are green. Same (single) eplusout.err warning on coincident/collinear vertices - that's fine.

In buildings with smaller rooms, addSkylights' built-in filters favour adding a single skylight strip (+ well) in the largest room:
Moving along ...

For the US DOE Warehouse, addSkylights first purges existing skylights (clean slate), before adding new skylight arrays to meet the requested SRR 4%.

Annoyed that Ruby'esque quirks remain in the Python implementation. Only catching these with runtime errors - my bad.
Otherwise, all unit tests (matching prior Ruby OSut unit tests) are green.
May test other US DOE Prototypes (and possible Canadian DND models) before merging.
Incrementally adding geometry-based functions (and unit tests).
