[newfield_revision Patch] Use std::abs, not abs

[Jeffrey Oldham]

We want to use std::abs() which supports double arguments, not abs()'s
integral arguments.

2001-08-16  Jeffrey D. Oldham  <oldham at codesourcery.com>

        * Pooma/PoomaOperatorTags.h (UnaryReturn<T, FnAbs>): Change abs()
        to std::abs().
        * Utilities/Tester.h (Tester::check(const char *, const T&, const
        T&, const T&)): Likewise.

Applied to      newfield_revision branch of examples/NewField/StatigraphicFlow/
Approved by     Stephen Smith
Tested on       sequential Linux using gcc 3.0.1 by compiling Pooma library and NewField tests

Thanks,
