Interface Summary

Interface	Description
IlblListener	An IlblListener is aware of changes to the Named range references.
IxtiListener	An IxtiListener is aware of changes to the Externsheet Ixti references.
Ptg	Ptg is the interface all ptgs implement in order to be handled equally under the eyes of the all seeing one, "he that shall not be named" A ptg is a unique segment of a formula stack that indicates a value, a reference to a value, or an operation.

Class Summary

Class	Description
Calculator

EngineeringCalculator
FinancialCalculator
FormulaCalculator	Formula Calculator.
FormulaParser	Formula Parser.
FunctionConstants	Function Constants for all Formula Types (PtgFunc, PtgFuncVar - regular and PtgFuncVar - AddIns) Modifications: all xlfXXX constants were originally in FunctionHandler getFunctionString was orignally in PtgFuncVar FUNCTION_STRINGS were originally in FunctionHandler getNumVars was originally in PtgFunc
FunctionHandler	Function Handler takes an array of PTG's with a header PtgFunc or PtgFuncVar, calcuates those ptgs in the determined way, then return a relevant PtgValue Descriptions of these functions are available on the msdn site, http://msdn.microsoft.com/library/default.asp?url=/library/en-us/office97/html/S88F9.asp
