Diff to previous 2609
Added string comparison to all Value object classes (to compare the
string value of an object to another string).

Overloaded perl '.' operator to do dot product when the operands are
formulas returning vectors.  (Part of the auto-generation of
formulas).

A few improvements to real and complex class output results.

Made Union class slightly more robust and removed need for makeUnion
method other than in the Union itself.

File length: 1924 byte(s)
Diff to previous 2606
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.

Can now specify that the objects stringify themselfs in their TeX
forms rather than their answer-string forms.  This makes it easier to
use the objects in the text of a problem (without having to call ->TeX
explicitly each reference).

Use

       Context()->texStrings

to start outputting TeX strings, and

      Context()->normalStrings

to switch back.

Added an Infinite object class for the Value package.  Still need to
add it to the Parser package.
