support edges within grid diagrams

[gavin-ts]

currently not supported since there is no edge routing mechanism for the grid layout

[alixander]

what if we only allow edges for adjacent cells (both row and column)? this could be easy to do and cover the vast majority of desired edges in grid diagrams

edges in grid diagrams are not supported yet

feature request: This issue could also add the ability to use grid on the blank canvas.

grid-rows: 1

x -> y

i underestimate how useful adjacent grid edges are. it's a huge feature. will prioritize
