Reflow Oven Controller

SimpleFlow-II

A PID based Reflow Oven Controller with Dual Thermocouples.  That's Two MAX31856's.

Now we can properly perform thermal profiling and handle those low volume builds.

What's more is we brought back the Bake function.  This is a necessary pre-work for PCB's and components before SMT process.

The controller is quite intelligent and have served us quite well.  We thought that many should also benefit from this.
