Computing dates when an LST is at night time

*Input Start LST and End LST should be given in the format hh:mm or hhmm
*Input Start Date should be given in the format yyyy-mm-dd

In the output table the word "night" on the first date when the LSTs fall entirely at night, and "day" on the first date when the LSTs sometimes cross into daytime.

This tool computes the dates where LST is at night time using the program nighttime (written by Mike Nolan)

Given LST Interval, Date and Number of days
* Start LST (hh:mm)
* End LST (hh:mm)

RA (J2000):	^hh ^mm
Dec (J2000):	^dd ^mm
