Thought I had already committed these.
Believe I have got the Gparity fermion force working.
* tests/Test_gpdwf_force.cc -- correctly predicts dS for two flavour pseudofermion
based on a small dt update of U field.
* tests/Test_hmc_EODWFRatio_Gparity.cc -- ran 1 trajectory on 8^4 with dH=0.21.
Need to accumulate a full plaquette log to believe fully which will take some hours of run time.
