Move violinplot into visualize.generic with option for splicing or expression data
change docc build directory ../gh-pages --> ../.gh-pages
comment out all of test_predict @mlovci please rewrite
rewrite logic of violinplot
Fix test_study tests
initial reworking of visualize predict/classify/graph
Got event/gene violinplots kind of working but renaming is weird with splicing
add feature ID shortener into BaseData, move _calculate_linkage into BaseData
Move _calculate_linkage to BaseData, so ExpressionData and SplicingData just instantiate it
Add argument for original, unstandardized data to DecompositionViz for violinplots
