Some code to get us going. Currently non-functional.
Merge branch 'master' into user-commands
Use new locator/authenticator for finding connection
Require URL parameter for listing users
Add `wp api user get-current` command
Remove args from class inline doc

WP-CLI doesn't seem to handle positional arguments here correctly, and
the format of these has changed with the locator/authenticator.
Fetch users from the API
`use` the CLI Formatter class
Use WPAPI classes for current user
Abstract item displaying for user data
Add `user get`
Add `user list-caps`
Add command descriptions
Merge pull request #9 from WP-API/user-commands
