Dervish Support for FORTRAN code

It is imagined that FORTRAN code is black-box numerical code. There is no real commitment to providing alot of call-outs to the FORTRAN programmer. Rather, we seek to allow code implemented in the Survey's idiom of FORTRAN to be linked into Dervish.

Dervish supports this in two ways:

CALL SH_ERROR ('AN ERROR OCCURRED') CALL SH_FATAL ('A FATAL ERROR OCCURRED') CALL SH_DEBUG (1, 'PLEASE NOTICE THAT...') The former two routines are called with a character string, the latter with a debug level and a character string. See the documentation for sh_error, sh_fatal and sh_debug.

HA! there is no C documentaion for these routines. Well, until we write some, you can tell the C programmers how to call these routines.
