Interaction with coastline

OpenDrift supports three different types of interaction with coastline/land:

To deactivate elements hitting the coastline (default for OpenOil and Leeway):

o.set_config('general:coastline_action', 'stranding')

To keep elements at coast until moved offshore at a later time (default for PelagicEgg):

o.set_config('general:coastline_action', 'previous')

For no interaction with coastline/land (default for WindBlow):

o.set_config('general:coastline_action', 'none')
