  Star.h - This is a header file used for adding all the necessary includes,
  some definition of structure types and some definitions of constants and
  macros, for the StarChart program.
  
  Credits for Star Chart:
       Robert L. Hill of the Orange County, CA. Amiga Friends User Group
                      wrote the original version of StarChart in AmigaBasic
                      The star data and many of the main functions of this
                      version are derived from that program.

       Ray R. Larson  wrote the c version 1.0 of StarChart, 'intuitionizing'
                      and enhancing the speed and functions of the original.
