    @class wxPropertyGridInterface

    Most of the shared property manipulation interface shared by wxPropertyGrid,
    wxPropertyGridPage, and wxPropertyGridManager is defined in this class.

    @remarks
    - In separate wxPropertyGrid component this class was known as
      wxPropertyContainerMethods.

    - wxPropertyGridInterface's property operation member functions all accept
      a special wxPGPropArg id argument, using which you can refer to properties
      either by their pointer (for performance) or by their name (for conveniency).

        Appends property to the list. wxPropertyGrid assumes ownership of the

        @remarks
        - wxPropertyGrid takes the ownership of the property pointer.
        - If appending a category with name identical to a category already in
          the wxPropertyGrid, then newly created category is deleted, and most
          recently added category (under which properties are appended) is set
          to the one with same name. This allows easier adding of items to same
          categories in multiple passes.
        - Does not automatically redraw the control, so you may need to call
          Refresh() when calling this function after control has been shown for
