/**
 * This class implements a method for converting from a two-digit year, such as
 * '82' to the four-digit '1982' equivalent. Due to the lack of information
 * contained in a two-digit year, the only valid years are 1970-2069.
 *
 * This class extends RegexStringParser only as a matter of convenience as its
 * decendents at the time of this refactoring all were decendents of
 * RegexStringParser.
