Add comment explaining that Infinity is defined in dangerousMacros.pl along with pi and sometimes
the complex version of i as well.

More updates to use the new Value->Package() call. This will make the
standard object-creation functions like Real() and Complex() use the
new lookup method.

Allow Compute() to create formulas as well as Value objects (with the
correct answer set to the original formula).
Also update some comments and formatting.

Added new Set object class to the Parser. It implements a finite set
of real numbers, for use with unions and intervals. E.g., (1,2) U {3}
or (1,2) U {3,4,5}. You can created Set objects in your perl code via
the Set() command, e.g, Set(3,4,5) or Set("{1,2,3}"). You should set
the Context to Context("Interval") if you plan to use Set objects, as
this defined the braces to form sets (rather than using them as
parentheses, which is the default WW behavior). Note that in Interval
context, you can NOT use braces as parentheses.
Current, Set objects are only allowed to be sets of numbers. It would
be possible to extend that in the future.

One more fix for handling intervals properly (I think it's really
right this time). Also, named constants that end in numbers will
produce TeX output with the number as a subscript (this was already
true for variable names).

Added a String type to the Value package. Mostly this is to make it
possible to generate an answer checker for it that uses the parser.
It also makes it more consistent for handling things like stringify,
especially when they are recursively called internally.
Added new default strings "NONE" and "DNE", since these get used a
lot.
Modified how the default parameters are set up for the answer
checkers, and how the answer checker reports the expected answer type
in type mismatch error messages.

Make Parser work with PGauxiliaryFunctions.pl, and add the macro files
needed to initialize the parser.
This form allows you to request diffs between any two revisions of this file.
For each of the two "sides" of the diff,
enter a numeric revision.
