created a nullable polymorphic owner for application and a configuration option to enforce its presence (default disabled)
fixed build issue due to Doorkeeper.configuration being stubbed
removed duplicate index
added an update generator to make migration simpler
merged with master
moved entire implementation out to a separate generator - tests required
finalizing tests
spelling error
more passing tests
final tests should pass
documentation correction
removed empty because I moved the code and spec to the expirable model but missed deleting this code
switched to using doorkeepr_token.accessible? to check if the token is invalid/expired/revoked
added token/info route to token_info#show controller action
added show action to token_info controller and removed tokeninfo from
the token controller
check that custom routes for token_info work from the dummy app
removed empty spec

Updating all development dependencies to recent versions.  Eliminating FactoryGirl deprecation warning
