-// Modifications done here:
-//
-// Original: clover term = 12x12 matrix per site
-//
-// But: Only two diagonal 6x6 hermitian blocks are non-zero (also true for original, verified by running)
-// Sufficient to store/transfer only the real parts of the diagonal and one triangular part
-// 2 * (6 + 15 * 2) = 72 real or 36 complex words to be stored/transfered
-//
-// Here: Above but diagonal as complex numbers, i.e., need to store/transfer
-// 2 * (6 * 2 + 15 * 2) = 84 real or 42 complex words
-//
-// Words per site and improvement compared to original (combined with the input and output spinors):
-//
-// - Original: 2*12 + 12*12 = 168 words -> 1.00 x less
-// - Minimal:  2*12 + 36    =  60 words -> 2.80 x less
-// - Here:     2*12 + 42    =  66 words -> 2.55 x less
-//
-// These improvements directly translate to wall-clock time
-//
-// Data layout:
-//
-// - diagonal and triangle part as separate lattice fields,
-//   this was faster than as 1 combined field on all tested machines
-// - diagonal: as expected
-// - triangle: store upper right triangle in row major order
-// - graphical:
-//        0  1  2  3  4
-//           5  6  7  8

-  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
