Diagram demonstrating a routing scenario.
Some prose documentation.
Start writing some tests
Allow FakeGearClient to be initialized with a dict of canned Units
Add ports and links to the Unit record so that it can be used in FakeGearClient to record the added units
Add a placeholder container_image for now
On Monday I need to find some way of adding the container image to the returned  records...
Merge remote-tracking branch 'origin/master' into discover-node-config-205
remove debug ines
Make FakeGearClient.list return Units without the container_image attribute for now.
Return a list of Applications
A test for multiple applications
A test for when there are no gear units
A note about the new image default
Don't import from a private module. Make Application public instead.
Add a test for the new Unit.container_image default.
Add some missing docstrings
Document the new units argument
More docstring fixes
Add some more flocker.node public APIs
