Make benchmark script extract all "content" downloads if no specific parameters are present
Print "Processing download ..." to STDERR, extractor results to STDOUT (because the first one is an informational message and the second one could be taken as "data")
Order downloads by downloads_id
Print out memory usage on each run_crf_model(InstanceList, CRF) run because apparently the Java class leaks memory
Increase memory available to Java to 1 GB because otherwise the extractor runs out of memory after 1000 extractions
Print out memory usage by default
