- PROGRAM:      Pyroelectric Measurement GUI
-
- PURPOSE:      Perform a pyroelectric current measurement with two-stage
-               temperature ramp control.
-
- DESCRIPTION:  This program provides a graphical user interface (GUI) for
-               automating a pyroelectric current measurement. It integrates a
-               Lakeshore 350 for temperature control and a Keithley 6517B for
-               sensitive current measurement. The experiment involves a
-               two-stage process: first stabilizing at a start temperature,
-               then ramping to an end temperature while logging data. The GUI
-               features live plotting and a detailed console.
