RandomLetter Macro
This generates a random letter up until the staticFrame number, at which point it
becomes a letter of your choosing.
Slate Macro
This generates a slate giving information on the show, animator, frame range, and so
on. Although you can use it to generate a frame, typically you attach it to the end of
your script before the FileOut. If you create the FileOut first, you can link the Slate to
print the FileOut file. You must precede it with a : (colon), for example:
:MyFileOut.imageName
The slate appears up to the markFrame parameter, which is 0 by default. It also loads
the script name and the frame range into the slate, adds the current date, and gives
you the option to stamp the current frame onto the output images.
