Examples

   ## A bit of a hack to not have a package dependency on hgu95av2
   ## but need to fiddle w/ the warn level to not fail the example anyways.
   curWarn <- getOption("warn")
   options(warn=0)
   on.exit(options(warn=curWarn), add=TRUE)
   if (require(hgu95av2)) {
     z <- buildChromLocation("hgu95av2")
   } else print("This example requires the hgu95av2 data package")
