gauge_ghost_wrapper is an internal class that is used to wrap instances of gauge ghost accessors, currying in a specific location and dimension on the field. The Ghost() accessors in gauge-field accessors return instances to this class, allowing us to then use operator overloading upon this class to interact with the Matrix class. As a result we can include gauge-field ghost accessors directly in Matrix expressions in kernels without having to declare temporaries with explicit calls to the load/save methods in the gauge-field accessors.
