+ * DESCRIPTION
+ * This sketch provides an example how to implement a Dimmable Light 
+ * It is pure virtual and it logs messages to the serial output
+ * It can be used as a base sketch for actual hardware.
+ * Stores the last light state and level in eeprom.
+ * 
+ * Developed by GizMoCuz (Domoticz)
+ *
+ * REVISION HISTORY
+ * Version 1.0 - January 30, 2015
