/**
  * The controller class handles all high-level functionality as well as
  * serial communication.
  * Its constructor can be seen as a replacement for the Arduino setup() function,
  * and its update() function as a replacement for the Arduino loop() function.
  *
  * For simplicity and ease of maintenance, the various components (valves, pumps and
  * pressure regulators) are represented by different classes that all inherit from
  * the Thing class. This way, the Controller simply has a list of pointers to Things,
  * and can call setValue and getValue to set and get the current state of each component.
  * This is implemented as a Map, to easily associate a ComponentID (which is communicated
  * via the serial link) to each instance.
