strange code for GenomicRanges:::compatibleStrand

[msannell]

Hi. I noticed some strange code in GenomicRanges (v1.38.0) for the
function GenomicRanges:::compatibleStrand. I believe that when
building GenomicRanges in R, the following happens:

1. R processes strand-utils.R, which defines an S4 generic for
   compatibleStrand stored in GenomicRanges:::compatibleStrand, and
   defines several S4 methods.

2. R processes findOverlaps-methods.R (this is processed after
   strand-utils.R, according to the "Collate" field in
   GenomicRanges/DESCRIPTION). This file defines a regular function
   stored in GenomicRanges:::compatibleStrand, overwriting the generic
   function defined in strand-utils.R.

Thus, this package defines several methods for compatibleStrand that
are never used, since there is no S4 generic function for it. Was
this intentional? It could be that the generic and methods are just
stale code that should be removed.

yikes! not good. I'll take care of it. Thanks for the catch.
