Requirement
-----------

Implement a class ``Hysteresis_nopoly`` (a Thermostat) that works as follows.

* It uses a sensor (a ``MockSensor_nopoly`` for now) to measure the
  temperature
* It controls a switch (a ``MockSwitch_nopoly`` for now)
* If the temperature falls below a certain configurable *low*
  threshold, the switch is set to *on* (heating is turned *on*)
* If the temperature rises above a certain configurable *high*
  threshold, the switch is set to *off* (heating is turned *on*)

Use the following tests to drive you through the exercise:
