First pass on viewerCanSeeOrDo & viewerAccessRights implementation. Added finer-grained viewerCanSeeOrDo switch to PersonSummaryRow & TeamHeader, so we turn off interface elements the person cannot access. Tested signin/signout, and confirmed that is still working. Registration requires manual browser refresh for signed in access rights to be recognized. Replaced loggedInPersonIsAdmin with viewerCanSeeOrDo & viewerAccessRights implementation. Control which PersonProfile we want to show with incoming prop. Working on bringing QuestionnaireResponsesList back to life. Implemented models/PersonModel - capturePersonRetrieveData. We may decide not to use person-retrieve in the future but I'd like to leave in place. #32
