### =========================================================================
### IMPORTANT NOTE - 4/29/2014
### Most of the stuff that used to be in the IRanges/R/Hits-class.R file was
### moved to the S4Vectors package (to R/Hits-class.R).
### The stuff that could not be moved there was *temporarily* kept here in
### Hits-class-leftovers.R but will need to find a new home (in S4Vectors
### or in IRanges).
