Profile our integration tests

[Boarders]

Currently some of the integration tests take an long time to complete. We should figure out where all the work is being done in those that take a long time to see where it is best to concentrate our performance tuning efforts. In particular the following tests are all over thirty seconds on my machine (those with a † take over a minutes):

• sankoff/single-block/huge-mix/1-2/test.pcg †
• sankoff/single-block/huge-mix/2-1/test.pcg
• sankoff/single-block/huge-mix/hamming/test.pcg
• sankoff/single-block/huge-mix/levenshtein/test.pcg
• dynamic/single-block/protein/L1-norm/invertebrates.pcg †
• dynamic/single-block/protein/discrete/invertebrates.pcg
• dynamic/single-block/protein/1-2/invertebrates.pcg †
• dynamic/single-block/protein/2-1/invertebrates.pcg †
• dynamic/single-block/huge-mix/1-2/test.pcg †
