Motor angle limits are not effective when both motors reach the limits (e.g., in the stance phase) #27

The motor angle limits warn any one motor before it reaches its hard stop.

However, when both motors are moving to pull the leg up, the effective range of 
motion of each motor is decreased because the two parts collide.

We need a way to keep this from happening. (Limit the sum of the two angles, 
perhaps?)

There might be something we can do to have the EtherCAT master coordinate 
communication between Medullas (or for itself to be the method of 
communication).

This problem cannot be solved in the medulla firmware level. We will have to 
implement safety modules in the master code to protect against this problem.
