Added ability to take a picture from a webcam
Right now I just have a main method in FacialRec that is doing this.
Current functionality:
- When run, starts a video feed from the webcam
- If user presses spacebar, takes a picture and displays it
- If user presses ESC or spacebar, return to video feed
- If user presses ESC, exit application
We might want to divide some of this into classes. Let me know what you think.
