| * Add better limit handling to system: when a limit is triggered, return to ↵damic0142019-10-292-0/+54
| | | | | | | | | | | | | | | | | | | | the linear-zero position. Add an initialize function for startup: use the limit switches to find the track extent and then go to zero. With the above two additions, we should be able to assume that new tests will always start at the zero position. Also add an initialize file which just calls sys.initialize to find the zero position. This should only be run on power-up (eventually, we should configure the Pi to run this on OS startup).
| * Add interrupts for HW limit switches.damic0142019-10-171-4/+85
| | | | | | | | | | Add ability to add SW limits (challenge mode). Add result file reporting (currently using date-time for the test, which we can assume will be unique per test).

* Add a linear encoder class for abstracting the angular-to-linear encoding, ↵damic0142019-10-151-4/+37

This is the basic implementation we've talked about, but there might be some issues still because the position is only read when we tell it, so keeping track of number of rotations might not be very accurate - will need to test and possibly brainstorm alternate ideas.
* Add System library and system test file. Still need to finalize some ↵damic0142019-10-135-8/+93
