--NOTES
--
-- NOTE A1: This template converts hands to inches/cm using
--      factors of 4x to get inches, or 2.54x for centimetres.
--      The calculations are in 4 different sections:
--         convert {1} & convert {3} in a range, or else
--         convert {1}, or else convert {1} with fraction.
--      Hence, the rounding of amounts is repeated 4 times, for
--      each of those 4 calculation sections. Due to complexity,
--      a fraction is only allowed for a single, not in ranges.

--HISTORY:
--11Jan2009 Created to show both inches & cm by default.
--07Jul2011 Put NOTES comments to explain template markup.
--07Jul2011 Put HISTORY to log major changes (not typos).
--07Jul2011 New parameter abbr=on for "h" or abbr=hh for "hh".
--07Jul2011 New parameter r=2 to round inches/cm to 2 decimals.
--07Jul2011 New parameter rinch=2 to round inches to 2 decimals.
--07Jul2011 New parameter rcm=2 to round cm to 2 decimals.
