Oauth2client-master

* Documentation for the library has
[switched to epydoc](http://google-api-python-client.googlecode.com/hg/docs/epy/index.html)
* Many improvements for media support:
+ Added media download support, including resumable downloads.
+ Better handling of streams that report their size as 0.
+ Update `MediaUpload` to include `io.Base` and also fix some bugs.
* OAuth bug fixes and improvements.
+ Remove OAuth 1.0 support.
+ Added `credentials_from_code` and `credentials_from_clientsecrets_and_code`.
+ Make oauth2client support Windows-friendly locking.
+ Fix bug in `StorageByKeyName`.
+ Fix `None` handling in Django fields.
[Fixes issue 128](http://codereview.appspot.com/6298084/).
* [Add epydoc generated docs.](http://codereview.appspot.com/6305043/)
* Move to PEP386 compliant version numbers.
* New and updated samples
+ Ad Exchange Buyer API v1 code samples.
+ Automatically generate Samples wiki page from `README` files.
+ Update Google Prediction samples.
+ Add a Tasks sample that demonstrates Service accounts.
+ [new analytics api samples.](http://codereview.appspot.com/5494058/)
* Convert all inline samples to the Farm API for consistency.

* Updated media upload support.
* Many fixes for batch requests.
* Better handling for requests that don't require a body.
* Fix issues with Google App Engine Python 2.7 runtime.
* Better support for proxies.
* All Storages now have a `.delete()` method.
* Important changes which might break your code:
+ `apiclient.anyjson` has moved to `oauth2client.anyjson`.
+ Some calls, for example, `taskqueue().lease()` used to require a parameter
named body. In this new release only methods that really need to send a
body require a body parameter, and so you may get errors about an unknown
`body` parameter in your call. The solution is to remove the unneeded
`body={}` parameter.

* Support for
[batch requests](http://code.google.com/p/google-api-python-client/wiki/Batch).
* Support for
[media upload](http://code.google.com/p/google-api-python-client/wiki/MediaUpload).
* Better handling for APIs that return something other than JSON.
* Major cleanup and consolidation of the samples.
