movie options

[GoogleCodeExporter]

A number of functions create a subdir full of image files that can be turned 
into a movie.

Create m-file that takes a folder and creates a movie, and have it auto called 
when all frames are rendered.  Change the argument to 'movie' to be the movie 
file name, the folder is a temp name that is cleaned up.

Allow for options like frame rate to be set

'movie', 'blah.mp4'
'movie', {'blah.mp4', 20}
