working ray-polygon collisions, but needs a lot of clean up
completed skeleton for the environment
world header file, with type definitions
Now runs at a reasonable speed.
Theta changes now.
Forgot to commit header file.
Motion works, but needs fine tuning.
Fixed bug in iterator.
Threading issues worked out better... Ready to add motion.
gaussian noise now has a gauss_init to initialize with a seed and chaos scalar
working gaussian nosie function: gauss_noise()
Started on drawing robots in the right place.
fixed the environment variable stuff
Free's shared memory in the core file upon error in forking or error in attaching to shared memory
Refactored simulator, set some stuff up to work with multiple robots.
moved stuff from robot_test into libsim.clibsim now contains the timer (pause/resume) stuff
Also commented andrew's code because it broke the build
Function to free memory added, not sure how to test if its working.
Fixed initialization of simulators struct
Added shared memory setup code to the create_robot function. Need to write the cleanup code still. Exec call is failing but wasn't succeeding before code change either.
Added signal handling code to core simulator
added a robot_test directory which contiains code to run the timer and deal with the robot side signaling. To compile it you need to run gcc robot_test/robot.c -o robot_test/robot. This whole file is temporary. It is just proof of concept until it gets added to the simulator library
Ooops, forgot to commit main method.
Added beginning GUI code, does not compile.
