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.

1fb41a4300 Added copyLane function to Tensor_extract_merge.h which copies one lane of data from an input tensor object to a different lane of an output tensor object of potentially different precision 
precisionChange lattice function now uses copyLane to remove need for temporary scalar objects, reducing register footprint and significantly improving performance
