Changes to 1.0.29

* A bit of a brown-paper-bag release since the last one had a crash
  on saving console output.  Also fix several other much less likely
  crashes.

Changes to 1.0.28

* Implement an adaptive Gauss-Kronrod integration and make it default
  for NumericalIntegral.  Adds functions AdaptiveGaussKronrod,
  AdaptiveGaussKronrodWithTolerance, GaussKronrodRule, and related parameters.
* SYNTAX: Don't special case parsing -<number>^n it will be parsed now
  as -(<number>^n) as it should be.  So -1^2 is now -1 as is only reasonable.
  Not sure what originally possesed me to parse it as it did, but it recently
  bit me because it makes no sense whatsoever.
* Fix referencing of true local variables so that local variables can be
  used as returns through the argument list.
* When first refering to a variable, only search the local context, otherwise
  we might be by mistake referring to an unrelated variable in the calling
  function or global.
* Add midpoint, trapezoid, and left-hand rule graphical examples showing
  the rectangles.
* Improve the Euler method exponential example
* Fix drawing points in postscript/PDF
* Allow graphing of constants (functions with no arguments)
* Add CompositeSimpsonsRuleData, TrapezoidRule, LeftHandRule, RightHandRule
  functions
* Argument now complains when given 0
* Fix Macaulay* functions when c=0
* Fix a few compile warnings
* Few minor bug fixes and fix some crashes
* Translation updates (Anders Jonsson, Yuri Chornovian, Martin Srebotnjak,
