Class
    Foam::geometricOneField

Description
    A class representing the concept of a GeometricField of 1 used to avoid
    unnecessary manipulations for objects which are known to be one at
    compile-time.

    Used for example as the density argument to a function written for
    compressible to be used for incompressible flow.
