-  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

-  // Some explanation of class structure for domain decomposition:
-  //
-  // Need a dirichlet operator for two flavour determinant - acts on both Omega and OmegaBar.
-  //
-  // Possible gain if the global sums and CG are run independently?? Could measure this.
-  //
-  // Types of operations
-  //
-  // 1) assemble local det dOmega det dOmegaBar pseudofermion
-  //
-  // - DirichletFermionOperator - can either do a global solve, or independent/per cell coefficients.
-  //
-  // 2) assemble dOmegaInverse and dOmegaBarInverse in R
-  //
-  // - DirichletFermionOperator - can also be used to 
-  //                                       - need two or more cells per node. Options
-  //                                       - a) solve one cell at a time, no new code, CopyRegion and reduced /split Grids
-  //                                       - b) solve multiple cells in parallel. predicated dslash implementation
-  //
-  //                                       - b) has more parallelism, experience with block solver suggest might not be aalgorithmically inefficient
-  //                                         a) has more cache friendly and easier code.
-  //                                         b) is easy to implement in a "trial" or inefficient code with projection.
-  //
-  // 3)  Additional functionality for domain operations
-  //
-  // - SchurFactoredFermionOperator  - Need a DDHMC utility - whether used in two flavour or one flavour 
-  //
-  // - dBoundary - needs non-dirichlet operator
-  // - Contains one Dirichlet Op, and one non-Dirichlet op. Implements dBoundary etc...
