    - #### addMember

          boolean addMember​(Principal user)

      Adds the specified member to the group.
      Parameters:
        `user` - the principal to add to this group.
      Returns:
        true if the member was successfully added, false if the principal was already a member.

    - #### removeMember

      Removes the specified member from the group.
      Parameters:
        `user` - the principal to remove from this group.
      Returns:
        true if the principal was removed, or false if the principal was not a member.

    - #### isMember

          boolean isMember​(Principal member)

      Returns true if the passed principal is a member of the group. This method does a recursive search, so if a principal belongs to a group which is a member of this group, true is returned.
      Parameters:
        `member` - the principal whose membership is to be checked.
      Returns:
        true if the principal is a member of this group, false otherwise.

    - #### members

          Enumeration<? extends Principal> members()

      Returns an enumeration of the members in the group. The returned objects can be instances of either Principal or Group (which is a subclass of Principal).
      Returns:
        an enumeration of the group members.
