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.

Significant update to new parser.

New features include:

  Better control over format of vector output (you can now
    specify ijk-format rather than <...> format)

  "Fuzzy" reals, where the relations like == return true when the
    two values are "close enough".  (This is controlable using
    parameters similar to those used in NUM_CMP).

  The fuzzy reals are now used in vectors/points/matrices/complexes/intervals
    and so on so that their relations will also be fuzzy.  E.g.,
    (1E-13,2) == (0,3) will be true, and norm(Vector(0,1E-13)) will
    equal 0.

  The two main portions of the parser (the Parser and Value packages)
    now share a common context object for configuration purposes.
