Convert Azimuth and Elevation to Right Ascension and Declination

Algorithm will convert Az/El angles to RA /DEC using a topocentric coordinate frame

Description

Function Description:
 AzEl2RaDec will take the Azimuth and Elevation in the local horizon reference frame, site latitude and longitude as well as a time in GMT and output the Right Ascension and Declination in the topocentric coordinate frame.

 List of Inputs:
 Local Azimuth Angle (degrees)
 Local Elevation Angle (degrees)
 Lat (Site Latitude in degrees -90:90 -> S(-) N(+))
 Lon (Site Longitude in degrees -180:180 W(-) E(+))
 UTC (Coordinated Universal Time YYYY/MM/DD hh:mm:ss)

List of Outputs:
Topocentric Right Ascension (Degrees)
Topocentric Declination Angle (Degrees)

Sample Function Call:
[RA DEC] = AzEl2RaDec(210.8250667,23.8595052,39.007,-104.883,'1994/05/14 13:11:20.59856')

Hi, I would like to know what are the local coordinate frame zero points and turning directions. I'm not even sure what are the official ones...

Nice code, thank you :)
Probably it is better to output Right Ascension in hours and not in degrees.
