    \ingroup plugins
    \ingroup network

    This plugin allows to interact with the \l{http://www2.meethue.com/}{Philips hue} bridge. Each light bulp connected to the bridge
    will appear automatically in the system, once the bridge is added to guh.

    \chapter Plugin properties
    Following JSON file contains the definition and the description of all available \l{DeviceClass}{DeviceClasses}
    and \l{Vendor}{Vendors} of this \l{DevicePlugin}.

    Each \l{DeviceClass} has a list of \l{ParamType}{paramTypes}, \l{ActionType}{actionTypes}, \l{StateType}{stateTypes}
    and \l{EventType}{eventTypes}. The \l{DeviceClass::CreateMethod}{createMethods} parameter describes how the \l{Device}
    will be created in the system. A device can have more than one \l{DeviceClass::CreateMethod}{CreateMethod}.
    The \l{DeviceClass::SetupMethod}{setupMethod} describes the setup method of the \l{Device}.
    The detailed implementation of each \l{DeviceClass} can be found in the source code.

    \note If a \l{StateType} has the parameter \tt{"writable": {...}}, an \l{ActionType} with the same uuid and \l{ParamType}{ParamTypes}
    will be created automatically.
