Log Message:
Some more corrections/additions in units.lib:
1. cables; US cables are 720 ft, but international cables are 1/10
nautical mile and UK Admiralty cables are 1/10 of 1853.2 meters
instead of 1852 meters. Make "cable" refer to the international
definition, and add "uscable" and "admiraltycable".
2. rods and chains. US rods and chains and furlongs are defined in
terms of US survey feet, not international feet. Since the US is
apparently working on retiring survey feet, it seems like the best way
forward on this is to define two sets of these units, one prefixed
with "us". Also since this file was inconsistent about using "survey"
vs. "surveyors", fill in more duplicates.
Furthermore, Gunter's rods and chains and links are as best I can tell
the same as the international ones, so since we already have
"gunterschain" add "guntersrod" and "gunterslink".
3. If we're going to make pf a special abbreviation for picofarad,
it's reasonable to make uf a special abbreviation for microfarad, and
if we're going to define "meg" for "megabyte" we should also have
"gig".
4. A "franklin" _is_ a statcoulomb, not an approximation of one.
5. "jewel" has two Es.
