v0.2.3

• Better control of Differential splicing initialization: the default "smart" initialization is now a one-shot method of moments estimator for the null model regression coefficients, but random initialization can be optionally specified, along with the seed (see --init and --seed options of leafcutter_ds.R) (issue #33)
• Dalila Pinto contributed a new script 'gtf2leafcutter.pl' for more robustly converting GTF files to the "annotation code" needed for leafviz. Thanks!
