1st solution to timer & producer-consumer problems
added first implementation for assignment 3
added narrow-bridge to Makefile.build and adjusted the test
semi working; before cleanup
we pass the test, but that doesn't mean it works
fixed one severe logic bug
still not working, but at least variables don't get corrupted anymore
added more fixes for logical bugs
fixed more logical errors and added output which facilitates debugging
+safety check
use semaphore to guarantee <= 3 cars on brigde
don't provoke crashes (aka switch direction while cars are still on bridge)
Merge branch 'task1_3' of github.com:pintos2013/pintos into task1_3
Improved the timer.c and updated the documentation
added debug switch, more docmuentation
Merge remote-tracking branch 'origin/ufuoma_proj1_q1' into task1_3
adjusted code so we pass the tests
+ random waiting; - debug functionality
more documentation
+ code style fixes
