Remove check_python for runtime coeff creation. Revert to load a file at runtime for the coeff instead. Ready tested in hashpipe and starts up. Ready to run with data to see what to fix next.

working on adding pfb thread into hashpipe. Have a include cuda error trying to have automake include it

Added a PFB version of the correlator. Also corrected the error checking in cuda_correlator to flag errors when error value was GREATER THAN the tolerance, rather than less than.
