14-Oct-98: initial release
16-Oct-98: reference to fitsio.h removed, also removed strings after #endif
directives to make gcc -Wall not to complain
20-Oct-98: added declarations NGP_XTENSION_SIMPLE and NGP_XTENSION_FIRST
24-Oct-98: prototype of ngp_read_line() function updated.
22-Jan-99: prototype for ngp_set_extver() function added.
20-Jun-2002 Wm Pence, added support for the HIERARCH keyword convention
(changed NGP_MAX_NAME from (20) to FLEN_KEYWORD)
