Set the default root object on a CloudFront distribution.

default_root_object.py

""" Need to serve some static HTML files, but can't use S3 because it won't
resolve index.html for you? Grab a CloudFront distribution from Amazon, point it
to your bucket, and set your index.html as the "default root object".

This code snippet uses the boto (http://code.google.com/p/boto/) Python package
to set the default root object on your distribution.
