+ * \brief The GuiController class
+ * \details Singleton class which is the main gateway of all signal/slots through GUI.
+ *          This class is the Gui gate keeper for decisions and will decide if a message should pass through the other observers.
+ *          Currently (08/30/2020) is a bridge and will pass all the messages.
+ *          Later with implementation/help of the Gui state machine will decide on the state of the device what needs to be done.
+ * \note    States are like [wait for user , user attention required , Time outs , ... ]
