2.2.0:
    Moved to httplib2, giving us cache and authentication.
    Sequences are now iterable (this should've always been the case).
    Sequence filtering is now much more pythonic: sequences can be filtered
        using generator expressions or list comprehensions.
    Removed old logger because it was too slow.
    Rewrote dtypes.py for consistency.
    Moved trim() function to a constrain() function that builds the dataset
    	instead of trimming it down.

    Responses (dds, das, dods, ascii, html, json, etc.) are now pluggable.
    Cleaned up the netCDF plugin *a lot*.
    Major improvements to the SQL plugin.
    Server should use environ['wsgi.errors'] for logging.
    Server uses Cheetah template for directory listing; templates can be
        overwritten to customize the server.
    Created a template for 'paster create'.

    Fixed small bug when deepcopy dtypes (data was not begin copied).
    Added a generic error catcher when the server fails.

    Some cosmetical changes to strip the leading '/' from the path.
