SMPUserManagerDelegate protocol

This protocol has to be adhered by any class that implements the success and failure notification delegates and this class has to be passed to the delegate variable of the user manager class object.

• userRegistrationFailed:( SMPUserManager *) method
  The failure listener delegate which will be called by the underlying framework when the user registration has failed and the reason for failure will be propagated through an error object.
• userRegistrationSuccessful:( SMPUserManager *) method
  The success listener delegate which will be called by the underlying framework when the user registration is successful.
