code: public static void setCollabNumberThumb(Context context, TextView initialsView, int collabNumber) {
          String collabNumberDisplay = (collabNumber >= 100) ? "+99" : "+" + Integer.toString(collabNumber);
          setColorForCollabNumberThumb(initialsView);
          initialsView.setTextColor(COLLAB_NUMBER_THUMB_COLOR);
          initialsView.setText(collabNumberDisplay);
      }
docs: Helper method to display number of collaborators. If there are more than 99 collaborators it
  would show "99+" due to the width constraint in the view.
