-  Policy implementation for G-parity boundary conditions
-
-  Rather than treating the gauge field as a flavored field, the Grid implementation of G-parity treats the gauge field as a regular
-  field with complex conjugate boundary conditions. In order to ensure the second flavor interacts with the conjugate links and the first
-  with the regular links we overload the functionality of doubleStore, whose purpose is to store the gauge field and the barrel-shifted gauge field
-  to avoid communicating links when applying the Dirac operator, such that the double-stored field contains also a flavor index which maps to
-  either the link or the conjugate link. This flavored field is then used by multLink to apply the correct link to a spinor.
-
-  Here the first Nd-1 directions are treated as "spatial", and a twist value of 1 indicates G-parity BCs in that direction. 
-  mu=Nd-1 is assumed to be the time direction and a twist value of 1 indicates antiperiodic BCs
