A simple example which retrieves metadata and a sample frame through multiple
methods: pycamhd.lazycache to both a local instance and the global
Google-hosted instance of lazycache, pycamhd.lazyqt and pycamhd.
For the local and global instance of Lazycache, and pycamhd.lazyqt, the movie
data is pulled from Rutgers.
For pycamhd as well as one of the test with the local version of Lazycache,
the movie data is retrieved from the local disk.
