#55 - Ultra precision voltage reference LTZ1000

This is my build of the KX reference designed by xdevs.com. Overall the project went very well. The reference worked on the first attempt. The output voltage was monitored for about 46 hours using HP 34401A and Datron 1071. The graphs look great overall, but with some small unexplained glitches.
