Merge pull request #100 from YeoLab/release/0.1.0

First release!

Minor performance issues and enhancements to follow in 0.1.1
Merge branch 'release/0.1.0' into dev

* release/0.1.0:
  Never standardize SplicingData, since it's already standardized from 0 to 1
  remove big block of commented code
  if feature_data is None, make an empty DataFrame for feature subsetting
  fix expressiondata and study tests
  actually move expression threshold
  move expression threshold cutoff to before log-transforming data
  move expression threshold to be on the raw data, not hte logged data
  Make sure set1 is only hex, not rgb colors
  Convert randomly assigned phenotype colors to hex colors from rgb
  Fix violinplots when there are not outlier cells, and
  Made "version" a required argument to Study (so "save" of a study bumps the version number correctly)
  fix feature_subset fixture for plot_pca test
  add test gene list
  fix test_external, remove test_ipython_interact
  Add official version
  increase scope of data_dir fixture
  remove pdb.set_trace()
fix default marker style
