CMoneyIDComparator
CMoneyIDValueComparator

specific comparators for comparing money values in various structs. These
are usually used when sorting arrays for the sort command, or in other places
when we need an array of money values sorted by amount or id.

This class compares money amounts for the Goldenseal job cost accounting software,
project management software, construction estimating software
and construction project estimating software.

SUPERCLASS = CTCS_ArrayComparator

Compare TCS 12/11/00
Compare two money id structs. We only compare the ID with this comparator.
Use it for finding objects rather than for sorting by value.
