Example: setpid --pitch -p 5.0

Support is not fully fleshed out because the quad
doesn't support everything. Some backend changes
will be needed to support the rest of the PID constants that
are in the design document.

Right now, the P and the D of pitch, roll, and yaw are
supported. The Height/Lat/Long PID controllers are
not supported by the quad<->backend protocol,
nor are the I constants of anything. The quad<->backend
protocol is aware of a Throttle controller, which is
nowhere in the documentation.

Just to get an idea of what the args will all look like

- Changed C standard
- Changed wpedantic to pedantic
- Deleted some unused code that used nonexistent time functions
- Fixed a bug with VRPN

Added nanosleep to make rate work right, also
switched from -t for total time to -c for count

Monitor should totally work, as should backend/frontend trackerdata updating

Because that's what it is.

Will have to write MODIFYING

website: Use Pelican instead of Jekyll for convenience

Summary
----
Switch out Jekyll in favor of [Pelican](http://docs.getpelican.com/en/3.6.3/index.html).

Pelican uses python, which allows us to create a python virtual environment in this project. This allows to run the project (optimistically) everywhere, without having to worry about everyone's local environments. This also works on the iastate linux computers if people are interested in using those.

Testing and Usage
----
I've tested this out on the iastate linux, and I can do the following:
1. Clone our project.
2. The first time the repo has been cloned, in the website branch, run "make setup"
3. Make a change to something in `website/content/pages`.
4. Run `make deploy` in the `website` folder.
5. See the results live at http://may1716.sd.ece.iastate.edu/
6. And no installation required!

This reverts commit 023cf74f.

Not really complete yet.

Pelican uses python, which allows us to create a python
virtual environment in this project to hopefully get to a point
where anywone can contribute to the website without any installation.
