6795bbca31 Generalized GeneralEvenOddRatioRationalPseudoFermionAction such that the multi-shift CG algorithm can be overridden by derived classes 
Added a mixed-precision variant of GeneralEvenOddRatioRationalPseudoFermionAction and a verification test against double prec class
Fixed non-const reference used in passing RHMC approx to multishift classes

d161c2dc35 Improved formating of timing output in mixed-prec multishift 
In test of mixed-prec multishift, added comparison against full double precision multishift both for timing and to cross-check the results

7a06826cf1 Added option to NerscIO to disable exit on failing plaquette check allowing for circumvention of factor of 2 error in CPS-generated G-parity config headers 
Adapted mixed-prec multi-shift test to new way to pass gauge BC directions and added cmdline option to perform the G-parity plaquette comparison with the corrected plaquette when loading config

1b84f59273 Added a mixed precision multishift algorithm for which the matrix multiplies are performed in single precision but the search directions are accumulated in double precision. 
A reliable update step is performed at a tunable frequency to correct the residual. A final mixed-prec single-shift solve is performed on each pole to perform cleanup if necessary.
A test is provided to demonstrate the algorithm.

a0ca362690 Added an RHMC pseudofermion action, GeneralEvenOddRatioRationalPseudoFermionAction, that works for an arbitrary fractional power, not just a square root 
Added a test evolution for the above, Test_rhmc_EOWilsonRatioPowQuarter, demonstrating conservation of Hamiltonian
Fixed HMC ignoring the MetropolisTest parameter of HMCparameters

249b6e61ec For G-parity BCs the Nd-1 direction is now assumed to be the time direction and setting a twist in this direction will apply antiperiodic BCs 
Added option to run Test_gparity with antiperiodic time BCs
