colorspinor_ghost_wrapper is an internal class that is used to wrap instances of colorspinor accessors, currying in a specifc location on the field. The Ghost() accessors in colorspinor-field accessors return instances to this class, allowing us to then use operator overloading upon this class to interact with the ColorSpinor class. As a result we can include colorspinor-field accessors directly in ColorSpinor expressions in kernels without having to declare temporaries with explicit calls to the loadGhost/saveGhost methods in the colorspinor-field accessors.
