if 2D geometry provided, ask user to provide elevation or query from public API

[dlebauer]

Currently it appears elevation is set to 115 by default

BETYdb-YABA/app/Meta.py

Line 140 in 31d6287

pt=pt+(115,)

• Short term fix - set to 0 by default
• Potential fix:
  • Better fix: ask user
  • Best: use lat/lon to query elevation from public API

@dlebauer I'd like to work on this issue, I would try to fix this by using the best method you described i.e to query from public API.
