cleanup, STRING reading actually only uses 1 way to read now
fixed network normalization: removed magic side-effect
network edges are now tuples instead of lists, making them immutable
checking already added edges with a set instead of a boolean hash for clarity
optimization: reduce size of the scoring network by only using actually available nodes
only save diagnostics files in the force function - we need it only there
parallelized retrieving of sequences for motifing greatly speeds it up
keep_memeout now only keeps the postprocessing iteration's files
added feature for KBase: save MEME sites to database
removed human_test, we will use a more flexible setup for user-defined runs in the future
Merge branch 'master' of https://github.com/weiju/cmonkey-python into build_debian
