Calculator for arrays.
This class is a RPN calculator on arrays. It uses classic push/pop/operator methods. That is, push array1, push array2, add, pop arrayResult.
2007-06-11 Jeff Anderson - Fixed bug in Push(Buffer) method. NAN was not computed properly.
2007-08-21 Steven Lambright - Moved the infix to postfix conversion into its own class.
2008-01-28 Steven Lambright - Added more support for the power operator
2008-03-28 Steven Lambright - Condensed math methods to just call PerformOperation(...). Converted valarray's to vectors (in order to use iterators)
2008-06-18 Christopher Austin - Added as well as fixed documentation
2010-02-23 Steven Lambright - Added Minimum2, Maximum2 and all min/max operations now ignore special pixels.
2010-04-08 Steven Lambright - Made min, max have proper implementations and vectors are now QVectors.
