code: function _viewRef( ref, comparisonViews ) {

docs: convert view named references to either current view
  or next view if the ID's match
  Makes it easier to access and build generic use cases
  
  @param  {string} ref current View ID
  @param  {array} comparisonViews - currentView and nextView string IDS
  @return {string} - new IDS if matched
