A trial version of a function for deep-cleaning a river network.
Sometimes a shapefile contains errors that are not obvious at an initial check, typically vertices that should not be there.
This function steps through each segment in sequence, and allows the user to interactively remove vertices.
cleanup_verts(rivers, startwith = 1)
A new river network object, see
rivernetwork
The river network object to use
The segment (number) to start with, defaulting to 1.
