Conditions for model generated output files; via var stand_alone and yes_print_output

[madMatchstick]

There are two output files, hyd.out and topmod.out, maintained from native topmod9502.c. Original source code boolean var yes_print_output currently overrides newly bmi-enabled variable standalone. I am proposing that standalone prevents any printed output, regardless of yes_print_output; may be more practical logic here?

Notes

• All doc mds, OUTPUT_FILES_EXPLAINED, STAND_ALONE, etc., accurately outline current bmi code behavior. See bmi.finalize()
• This is NOT A BUG, but a sensible suggestion...

Current behavior

stand_alone	yes_print_output	out files generated?
TRUE	TRUE	YES
TRUE	FALSE	NO
FALSE	TRUE	YES
FALSE	FALSE	NO

Proposed behavior

stand_alone	yes_print_output	out files generated?
TRUE	TRUE	YES
TRUE	FALSE	NO
FALSE	TRUE	NO
FALSE	FALSE	NO
