class MESet():
    """ The Mutually Exclusive set allows for the grouping of objects to allow easy selection of related items. For instance, a group of buttons could be grouped so that selecting one button deselects the others in the group.

    Compatible extronlib classes:
        - IOInterface (and any children):
            - extronlib.interface.RelayInterface
            - extronlib.interface.FlexIOInterface (Output only)

            - extronlib.interface.SWPowerInterface
        - Button:
    
    ---

    Arguments:
        - Objects (list) - list of compatible objects
    
    Note:
        - Each object must have a method SetState.
        - SetState must take an integer argument.
        - Any object with a SetState function that takes an integer object is compatible with this class.
        - A programmer can create their own class and use it with MESet.
