Notes

To compile: USE MAKEFILE NOW! This below info is out of date.
gcc -Wall -g -o tutorial main.c callbacks.c -export-dynamic `pkg-config --cflags --libs gtk+-2.0`
or to use gtk3: 
gcc `pkg-config --cflags gtk+-3.0` -o tutorial main.c `pkg-config --libs gtk+-3.0`
newest:
gcc -std=gnu99 `pkg-config --cflags gtk+-3.0` -o tutorial main.c callbacks.c vision.c pololu.c -export-dynamic `pkg-config --libs gtk+-3.0` -lm `pkg-config --cflags --libs opencv`


for cpp:
g++ -std=gnu99 `pkg-config --cflags gtk+-3.0` -o tutorial main.c callbacks.c vision.c pololu.c -export-dynamic `pkg-config --libs gtk+-3.0` -lm `pkg-config --cflags --libs opencv`


To run program: 
./tutorial



To do:
openCV not compatible with gtk3???? To fix, remove some linkers for opencv 
OR remake openCV with gtk3 compatibility       GTK3=ON     http://stackoverflow.com/questions/22029939/opencv-getting-picture-from-default-webcam-in-c-c-gtk-issues
OR use gtk2 always.
**SOLVED by reverting to gtk2**


VIDEO:
*Show b/w image on command in gui
*Show b/w image video in gui
*Add video controls in gui
*Add simple openCV mods to video
*Detect object
*Draw image position and other info on video
*Record video
*Complete button assignments
Fix segfaults from spinbutton changes. **cannot track down the problem...
*Register keystrokes
Add second camera. Need new firewire port

Implement PID controller



CONTROL:
Install DAQ
Command current to motor drivers


IMAGE DETECTION:
Better algorithm for general shape:
