New module to import and process benchmark output
This is the beginning of a module to import and process benchmark outputs. The module currently supports importing of a bench.out and validating it against a schema file. In future this could grow a set of routines that benchmark consumers may find useful to build their own analysis tools. I have altered validate_bench to use this module too. * benchtests/scripts/import_bench.py: New file. * benchtests/scripts/validate_benchout.py: Import import_bench instead of jsonschema. (validate_bench): Remove function. (main): Use import_bench.
