exonCompatible: Compatible fragment counts for exons
In ldg21/SGSeq: Splice event prediction and quantification from RNA-seq data

Identify fragments compatible with exons.

1 2	exonCompatible(exons, spliceL, spliceR, frag_exonic, frag_intron, counts = TRUE)

`exons`	`IRanges` of exons
`spliceL`	Logical vector indicating whether LHS boundary is spliced
`spliceR`	Logical vector indicating whether RHS boundary is spliced
`frag_exonic`	`IRangesList` of exonic regions, one entry per fragment
`frag_intron`	`IRangesList` of introns, one entry per fragment
`counts`	Logical indicating whether counts or indices of compatible fragments should be returned
