[newfield_revision Patch] StatigraphicFlow: Linear Algebra into ScalarCode

[Jeffrey Oldham]

This patch moves the statigraphic flow's linear algebra computation
into a ScalarCode object, improving correctness.  The code now
compiles excepting two missing mesh functions.  One removing
pseudocode section needs rewriting using mesh functions.

        * StatigraphicFlow.cpp (findIndex): Moved into ComputeGradients.
        (ComputeGradientsInfo): New structure to support scalar flow code.
        (ComputeGradients): New structure for linear algebra ScalarCode.
        (main): Revise pressureGradient's type to a vector.  Move linear
        algebra computation to a ScalarCode object.  Remove FIXMEs for
        sum().

Tested:         compiled using sequential Linux gcc 3.0.1
Approved by:    Stephen Smith
Applied to:     newfield_revision branch
