There are more than 300 library functions in our core LIBBN library. As a core library used by nearly every one of BRL-CAD's tools, testing those functions for correct behavior is important.

References:

• include/bn.h
• include/plot3.h
• include/vmath.h
• src/libbn/qmath.c
• src/libbu/tests/*.c (note libbu, not libbn for examples)
• src/libbn/tests/*.c

This task involves implementing a new unit test for any of LIBBN's plane.c public distance functions:

grep -E '^bn' plane.c  | sort | cut -f1 -d\( | sort | grep _dist_
