/**
 Users can add dimmers, a particular kind of switch that can also modify the intensity level of a given light.
 There are two types of dimmers:
 • A dimmer with state stores a given intensity level and sets the light to that level. <-- StatefulDimmer
 • A dimmer without state can just increase or decrease the intensity of a light. <-- DefualtDimmer

 The user can change the state of a dimmer through an intuitive UI in SmartHut .
