* \brief Thermo-control driver.
*
* This module implements multiple thermo controls, which is the logic needed to try
* keeping the temperature of a device constant. For this module, a "device" is a black box
* whose temperature can be measured, and which has a mean to make it hotter or colder.
* For instance, a device could be the combination of a NTC (analog temperature reader) and
* a Peltier connected to the same physic block.
*
* This module relies on a low-level driver to communicate with the device (implementation
* of the black box). This low-level driver also controls the units in which the temperature
* is expressed: thermo control treats it just as a number.
