;
; Welcome to MarSoft. The GDL library created for Ursinus College Physics Department.
;
; Useful abbreviations to know:
; - RA = Right Ascension
; - RAh = Right Ascension Hour(s)
; - RAm = Right Ascension Minute(s)
; - RAs = Right Ascension Second(s)
;
; - Dec = Declination
; - DecD = Declination Degrees
; - DecM = Declination Minutes
; - DecS = Declination Seconds
;
; It contains a search feature with two options:
; - Search a .CSV file
; - The .CSV file columns must have the following format to be read properly:
; - Source Name, RAh, RAm, RAs, DecD, DecM, DecS
; - Searching with Observation Time and Date
;
; It contains a calculation feature with four options:
; - Calculate Day of the Year, also known as Day of the Julian Calendar
; - Calculate Declination of the Mean Sun using either:
; - Day of the Julian Calendar
; - Days since Vernal Equinox
; - Calculate Right Ascension of the Mean Sun using either:
; - Day of the Julian Calendar
; - Days since Vernal Equinox
; - Telescope Calculations
; - Calculate Angular Magnification
; - Calculate Angular Resolution
; - Calculate Focal Ratio
; - Calculate Snell's Law For Angle Of Refraction
