JOSM/Plugins/Shrinkwrap

Shrinkwrap is a JOSM plugin that offers three actions to create:
- A convex hull around the selection
- A "shrinkwrapped" way (concave hull) around the selection
- A "ballooned" way (inner concave hull?) around the cursor
See https://github.com/ubipo/shrinkwrap for more documentation and usage instructions.
