A class for locking the laser using a transfer cavity. The controller reads the voltage fed to the piezo of the cavity, the voltage from a photodiode measuring the light from a master laser (He-Ne) and a further n photodiode signals from n lasers you're trying to lock. The controller then fits a lorenzian to each of these datasets, and works out what to do with each slave laser to keep the peak distances the same. In the hardware class, you need to make a TCLConfig and populate all the fields of that TCLConfig.
