answer evaluators to be called twice.  (Specifically the error flags are initialized
at the beginning of each call to evaluate).

Modifications in these two files make questions whose answer blanks hve
the same names behave properly.

The new versions of CGI seem to return such answers as a reference to an array.
Earlier versions returned the answrs as a string with \0 separators.

With the new changes the AnswerEvaluator get_student_answer subroutine and
the NAMED_ANS_RULE in PGbasicmacros.pl will handle either a null separated
string or an answer array when dealing with vector answers.

This should correct some difficulties experienced in the linear algebra
questions.  More testing needs to be done.
