Fixed the problem I pointed out at MathFest where some errors were not
being reported in the traditional num_cmp() function.  (Things like
'x+3' in a numeric field would not be reported as an error and x would
be treated as 0).  This is due to a change in version 1.14 when Sam
was normalizing the error reporting code; he didn't notice that warn
had been rerouted to die in PG_answer_eval().  I have replaced it.

Fixed grade_problem so taht is uses the safe compartment.  (This is
important because the problem can supply its own grader, and that code
shoudl be run in the safe compartment, just like the answer checkers
are.  Without this, graders could call PG_restricted_eval() and
actually get access to the full WW environment rather than the safe
compartment.)

Fix use of $SIG{__WARN__} and $SIG{__DIE__}.

* Each change to $SIG{__WARN__} and $SIG{__DIE__} is now dynamically
scoped with "local", rather than changing globally and then restoring at
the end of the block.

* The special value "DEFAULT" is used instead of sub {CORE::die(@_)} or
sub {CORE::warn(@_)} when preparing to eval STRING code.

* Where $SIG{__WARN__} and $SIG{__DIE__} are overridden to do
preprocessing with PG_errorMessage, the previously installed handlers
will be called instead of the built-in warn or die functions after
preprocessing occurs. (For example, the warn and die handlers defined in
Apache::WeBWorK or the warn handler defined in WeBWorK::PG will be
called.)

* The behavior in process_answers is modified so that the custom
handlers are installed once before the answer evaluation loop. This
causes them to be in effect during the setup/teardown code, but I don't
think this will be a problem.

Allow subclasses of AnswerEvalutor to be used.  Check for a match
with a substring AnswerEvaluator instead of equality.

Undoing some of the temporary changes I made to the warn message.

This may break what happens with xmlrpc however. (sigh)

Temporary modifications which allow the Warning mechanisms to work when
using the XML access methods.

This needs to be looked at again.  There is also a problem with defining
permissions for creating directories.  There is a temporary #FIXME
that seems to work.

Diff to previous 2167
Add better error reporting in PG translator.  In particular, these
changes add two new features:

	1)  produce a full stack trace when a .pg file dies, and
	2)  convert (eval nnn) references to filenames, when
	    possible, in warn and die messages while processing a
	    .pg file.

There is also a change in the webwork tree that is needed to make this
all work, so be sure to apply updates in both trees.

We are using our own version of strict.pm that has a require Carp;  commented out.
This is included in be_strict which is used to implement strict within PG macro files
which need to be evaluted inside the Safe compartment

Replaced PGsort with a version that uses quick sort.  This fixes the
problem the old PGsort had with Perl compiled with ithreads.

changed the way the IO modules work: shared subroutines are in IO now,
and IO has a hash %WeBWorK::PG::IO::SHARE which can be added to
Translator's %shared_subroutine_hash directly.
