Fixed bugs in lattice gauge field interface.
Corrected formatting of call to np.zeros in measurement creation.
Changed saving of props and configs so they're stored as archive of multiple files.
Added code to allow configurations and props to be saved to an npz file.
Added code to allow saved configurations to be loaded by the simulation script.
Added function to convert to CUSP matrix format.
Added cuda preprocessor directives.
Semi-working cuda configuration
Semi-working cuda configuration
Got it working - wasn't converting matrix properly
Merge branch 'master' of ssh://orentago.linkpc.net:535/pyQCD
Moved timer to before lattice construction
Removed GPU code as this'll be merged later from other branch
Optimized nearest neighbour determination in constructor
Corrected bug in timing code, which didn't account for start time
Merge branch 'master' of ssh://orentago.linkpc.net:535/pyQCD
Cuda branch taken from origin
Removed merge syntax from files
Set up cuda to return propagator - matrix multiply changes object it uses, so need temp var
Improved performance a bit
