Create a GRG that takes input breaklines into account

As a user I need to create a GRG that takes existing natural break lines into account. User should be able to upload a set of features that should split any polygons generated by the GRG tool. For example, major rivers, main highways, ridge lines. Tool should allow for a minimum polygons size to be set to avoid "splinter" polygons. Splinters to be dissolved into an adjacent poly (but shouldn't be dissolved across a break line). Tool should warn when too many features are uploaded. E.g. someone submits the Redlands streets network as breaks. Tool should say this is too many - select the most important lines (major roads, highways) and try again.

After processing, results should be interactively adjustable before publish. Should get preliminary numbers, but the user should have a set of tools to adjust the data, to include: a) Merge tool - click a segment and it disappears, the polygons on either side merge. b) Split tool - sketch a line across a polygon to split it. c) Undo tool - reverses last action. d) renumber - after geometries adjusted, user should be able to trigger a renumber of the polygons.
