+This program is meant to make the process of collecting the BJD, rel flux, and the rel flux error from AIJ Excel
 spreadsheets faster. The user enters however many nights they have and the program goes through and checks those text
 files for the different columns for: BJD, rel flux, rel flux error from TESS.
