-/**
-* UnitConvertor is able to convert between different units and currencies.
-*
-* @author Stanislav Okhvat <stanis@sibfair.nsk.su, stanis@ngs.ru>
-* @version $Id: UnitConvertor.php,v 1.00 2002/03/01 17:00:00 stasokhvat Exp $
-* @package UnitConvertor
-* @access public
-* @history 01.03.2002 Implemented the code for regular and offset-based
-* conversions
-*
-* 13.12.2004
-* By Chris Hansel (CVH): changed getConvSpecs in order to have it look up
-* intermediary conversions (also see comments in check_key).
-*
-* Intermediary conversions are useful when no conversion ratio is specified
-* between two units when we calculate between the two. For example, we want
-* to convert between Fahrenheit and Kelvin, and we have only
-* specified how to convert Centigrade<->Fahrenheit and
-* Centigrade<->Kelvin. While a direct (Fahrenheit->Kelvin) or
-* reverse (Kelvin->Fahrenheit) lookups fail, looking for an intermediary
-* unit linking the two (Centigrade) helps us do the conversion.
-*
-* 13.12.2004
-* Chris Hansel (CVH): $to_array argument of addConversion method can now
-* contain units as 'unit1/unit2/unit3', when all units stand for the same
-* thing. See examples in unitconv.php
