Add python script that diffs VTKM benchmarks.

# Compares the output from BenchmarkDeviceAdapter from the serial
# device to a parallel device and prints a table containing the results.
#
# While this was written for the device adapter algorithms, it could be used
# to compare any VTKM benchmark output.
#
# Example usage:
#
# $ BenchmarkDeviceAdapter_SERIAL > serial.out
# $ BenchmarkDeviceAdapter_TBB > tbb.out
# $ devAlgoBenchSummary.py serial.out tbb.out
#
#
# The number of threads (optional -- only used to generate the "Warn" column)
maxThreads = 4
#
# Print debugging output:
doDebug = False
#
# End config options.
