[newfield_revision] patch: FieldShiftEngine

[Stephen Smith]

 <<06Aug.field.shift.patch>> 
This patch combines two sets of changes:
1) FieldShiftEngine.h supports a shifted view of a field, to support the
syntax f(fieldOffset, centering), which allows you translate between fields
with different centerings.
2) I also incorporated changes sent by J. Oldham to clean up the tests in
new field.  (CrossBox.cpp changed to use new centerings, ExpressionTest.cpp
fixed the name at the end, alphabetized makefile targets.)

Tested with KCC under linux.  Reviewed by Jeffery Oldham and myself.
