@joshuacortez I've implemented boundary based on our discussion in #33 Can you take a look at https://geowrangler--pr47-feature-improve-grid-p6aovzwo.web.app/tutorial.grids.html#Reusing-boundaries to see if this makes sense or if you have other comments?

@jtmiclat I looked at https://geowrangler--pr47-feature-improve-grid-p6aovzwo.web.app/tutorial.grids.html#Reusing-boundaries and it makes sense! Just wondered what this cell was for

from importlib import reload

reload(grids)

[jtmiclat]

Whoops, leftover when I was debugging something. It reloads libraries in case you import them but then changed the module. Ill remove it.
