    Most of the shared property manipulation interface shared by wxPropertyGrid,

    - 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
