Initial full order observer build with Matlab linking.
Implement full order observer.

This implementation requires Matlab to be called from C++.  Check yourself
before you wreck yourself.
Output 101 speeds instead of 11.
Merge remote-tracking branch 'oliverlee/fullorderobs' into full_order_observer
Reformat generated floating point to have 'f' suffix.

Three runs were done with this commit.
Compute discrete state space observer closed loop evals.
Merge remote-tracking branch 'oliverlee/fullorderobs' into full_order_observer
Fix bug in observer A matrix.

Previous commit had observer A matrix equal to plant A matrix, instead of
A-K_obs*C. This results in a observer that has unstable dynamics since the
plant dynamics are unstable.
Update observer state before estimation start.

Continuously update the observer state with measurement data (steer,
lean rate, steer rate) while not estimating.
