a3243097c7 - big change to PID class. It was not properly handling the integral. 
Essentially it was never large enough to impact the loop. The integral
has been inverted so if you want more integral, define it as a smaller
number.

Update oven.py 
Added proportional output funtionality by turning the oven (SSR) on for a portion of the time_step determined by the pid loop output. So, if time_step = 1, and the pid loop is calling for .3 heat, the SSR will be on for .3 seconds, and off for .7 seconds.  I did this by adding an additional sleep.  Previously, the SSR would be on whenever pid > 0.

9ca2842b0e unary operation made safe in error handler for Thermocouple 
unary & is used with 32 bits operands. If the operand literal is not
explicitly expressed as  32bits, it can create random casting errors
depending on the Python version and the underlying implementation.

00ed33b002 Added non responsive sensor emergency stop 
Added an 'emergency stop' feature to stop a run if the temperature
sensor is no longer providing data.  If the temperature sensor values
are remaining stable and exactly the same for 20 time cycles
consecutively while the heat is on, the run is reset to prevent damage
to the part or the oven.
