Exposure Time Calculator for the Giant Magellan Telescope Multi-object Astronomical and Cosmological Spectrograph
Desiged for the Munnerlyn Astronomical Instrumentation Lab at Texas A&M University Coded by the Kwisatz Haderach in 2018, based on previous versions by Ting Li

TODOs:
- output all the re-parsed data so it doesn't have to be calculated every time
- add input disabling for plot calls that don't require them
- math problem somewhere in signal/noise ratio?
- add the loading screen (last)
Ok soldier listen up! Here's the query map!
