Percent inclusion in sig_introns.tsv

[kyleb512]

The export table function in this package is a great addition. However, I was also hoping that it would include two additional columns for the percent inclusion per intron for each group in addition the the delta psi between the conditions (the numbers displayed on top of each arc on the leafviz graphs). This would allow me to search for introns which have large changes (>90% to <50%), compared to currently filtering by delta psi which can return relatively large changes but which are still very small scale (0.00002% to 0.002%). Thanks!
