Fixed a rendering issue with movement/todo.md.
Added a zmq python demo.
Fixed the demo zeromq code to use a non-blocking approach.
Updated .gitignore to ignore vim, Python, and C++ byproducts.
Added configuration_settings.json.

This is a first jab at a settings file. I'm giving it a very restrictive
name to suggest that other types of settings can (and should) exist in
a similar file.
Started grapevine.py, which defines a communication object.

This is untested, not fully featured, and incomplete.
Added publisher and subscriber contexts.

Again, this isn't tested/working (class calls).
Communicator object now works.

This includes basic functionality. I still need to do a proof read and
add comments before sending it through a review process however.
Release candidate 1 for grapevine.py.

This introduces a communication protocol for robosub modules.
Added a demo beaglebone script.

This has more functionality than we really need, and it assumes more
pins than we plan to demo with.
Created demo code for the beaglebone.
Made minor modifications based on cevans87's CR.
Fixed a usability issue with grapevine.py.
Fixed a typo.
Merge branch 'user/LoganEvans-structure' into feat/communication
Merged user/LoganEvans-structure and updated .gitignore.

This adds grapevine.py, which fulfils the python module communication
requirements.

CR: BigDCross, cevans87
Added vision settings and individual camera folders.
Moving the microcontroller com demo file.
Merge branch 'feat/communication' into user/LoganEvans-serial_interface

Conflicts:
	.gitignore
Adding a some publishing code to the serial demo.
