Add tests for situations in which Authorization redirects.
Don't return Provider::Error as a response to Provier.parse(). Instead, inject the error into an Authorization or Exchange.
Move Provider::Authorization#response_body return nil -- the user should call valid? and render their own error page.
Add error page for the example app.
Update README for adjusted Authorization error handling.
Remove some debugging lines.
Fix typo in README.
Return no headers for Authorizations that redirect.
Fix some problems with the example app.
Regenerate access token when an already-authorized client tries to authorize with response_type=token.
Expose a method for parsing an access token out of a request.
Take Rack env objects instead of request objects from frameworks.
Require rack.
Use factory_girl ~> 2.0.
Put in rack.input if it's missing.
Cope with missing Rack fields that Rails controller tests don't populate.
Use Rack::MockRequest to fix missing fields.
Apparently Rack::Test doesn't send REQUEST_URI sometimes.
Check we don't have the same LF->CRLF problem that Facebook does.
removed deprecation warning on set_table_name
