Copyright (c) 2004 by Marco van de Voort

An implementation for unit convutils, which converts between
units and simple combinations of them.
Based on a guessed interface derived from some programs on the web. (Like
Marco Cantu's EuroConv example), so things can be a bit Delphi
incompatible. Also part on Delphibasics.co.uk.
Quantities are mostly taken from my HP48g/gx or the unix units program
