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

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
