Renamed original script to _solo, updated the main script to allow for multiple character takes (based on script parameters)
eg.

Calling the script with 3 arguments:
> too_many_cooks.sc "Smarf" "Lars Von Trier (as “Pie”)" "Katie Adkins"

This will show the following prompts, requesting keyboard input before taking the photo sequences:
> Get Smarf to sit in front of the camera, press any key when ready:
> Get Lars Von Trier (as “Pie”) to sit in front of the camera, press any key when ready:
> Get Katie Adkins to sit in front of the camera, press any key when ready:

In each case, the webcam will start up, the computer will beep when the photos are starting and ending (2.5 seconds worth)
