Flatten Compressed Exons

The "flattenCompressedExons" transform flattens "delta encoded" exons. The transform inputs the start coordinate of the gene body and a comma-delimited string of alternating intron and exon lengths. A new data object is created for each exon.

This transform is mainly intended to be used with an optimized gene annotation track. Read more at Annotation Tracks notebook.
