Made sure that num_cmp, fun_cmp and str_cmp return an
answer evaluator when used in scalar context. In other words
$ans_eval = num_cmp(234);
will now work as expected -- you will get one answer evaluator which
checks whether the answer is 234.
Previously you had to write:
($ans_eval) = num_cmp(234);
or else you would have the numeral 1 placed in $ans_eval since
that is how many answer evaluators were created.

Modified NUM_CMP so that it always places a numerical value in
$rh_ans->{correct_ans} even when the original answer is an
exression to be evaluated by perl.
Also modified prfmt so that it doesn't try to format arithmetic
expressions using sprintf

Added a default value for tolerance to is_zero_array
macro and removed the allow_unknown_defaults value.
Changed the call to is_zero_array from tol to tolerance in
FUNCTION_CMP.
Previously, because of the mislabeling of 'tolerance' as 'tol' the
tolerance value could not be set and was always being
set to a default value.

Added pod comments to PGanswermacros for some of the filters.
I also rearranged the structure of the file slightly to make it
easier to add the pod documentation.

Changed NUM_CMP so that the calculated versions of the student's answer
and the professor's remain in the answer hash to be displayed by
displayMacros.
There are now slight clues, when using num_str_cmp that the
instructor's answer is a string. I'm not sure anyone can find them
easily. Further refinements should be able to remove them in any case.

Simplified some of the scripts. Using forking there is no need
to evaluate $main:: everytime, since it remains the same for both
the parent (where the script is compiled) and in the child where
the script is executed.
There were other minor fixes to work around bugs in 5.6.0 which were
fixed in 5.6.1
