RFA: Permit NoGeometry Fields to Instantiate

[Jeffrey Oldham]

OK to commit?

These changes with my two previous proposed patches permit compiling
this program:

    #include "Pooma/NewFields.h"

    #define T1 NoGeometry<(int)3>
    #define T2 int
    #define T3 CompressibleBrick
    #define T4 Interval<(int)3>
    template class Field<T1,T2,T3>;
    template class View1<Field<T1,T2,T3>,T4>;

This program adds the "class Field" line to what Dave Nystrom
originally requested.  This reflects circular references in the
definition of View1.

Please carefully check the patch to see if its semantics match those
you believe they should.

        * NewField/FieldEngine/FieldEngine.NoGeometry.h
        (FieldEngine<NoGeometry<Dim>, T, EngineTag>): Add a default
        constructor.
        (FieldEngine<NoGeometry<Dim>, T, EngineTag>)::physicalDomain): New
        function.
        (FieldEngine<NoGeometry<Dim>, T, EngineTag>)::totalDomain):
        Likewise.

Tested on       sequential Linux gcc 3.0 by compiling Pooma library
