Class: NumberComparator  - X-Ref

NumberComparator compiles a simple comparison to an anonymous
subroutine, which you can call with a value to be tested again.

Now this would be very pointless, if NumberCompare didn't understand
magnitudes.

The target value may use magnitudes of kilobytes (k, ki),
megabytes (m, mi), or gigabytes (g, gi).  Those suffixed
with an i use the appropriate 2**n version in accordance with the
IEC standard: http://physics.nist.gov/cuu/Units/binary.html

Based on the Perl Number::Compare module.
