// You typically run this view controller by:

//

// 1. creating it with credential data of a supported type

// 2. setting yourself as the delegate

// 3. optionally set the URL

// 4. presenting it modally

//

// If the user taps Cancel, your -identityView:didChooseIdentity: delegate method 

// will be called with kCredentialImportStatusCancelled.

//

// If the user successfully imports the credential, that method will be called with 

// kCredentialImportStatusSucceeded.

//

// Finally, if the import fails for some reason, your delegate callback will be 

// with kCredentialImportStatusFailed.  You are responsible for displaying this 

// error to the user.

//

// When you're done, dismiss the view controller.
