CCostIDComparator
CCostNameComparator
CCostItemNumComparator

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

Comparators are a convenient way to sort a struct array based on the value
in one of the members. These sort cost item name arrays by id, item number or name.

SUPERCLASS = CTCS_ArrayComparator
