Feature request: flexible distance ranges in plotDistToTSS()

[perinom]

Great tool, thanks a lot!

Quick question:
The distance bins used by plotDistToTSS() seem to be hard-coded into lines 52-55 of plotDistToTSS.R. Would it be possible to turn them into function parameters?

  ## assign Feature according to the distancetoFeature
   peakDist$Feature <- NA
   limit <- c(0, 1000, 3000, 5000, 10000, 100000)
   lbs <- c("0-1kb", "1-3kb", "3-5kb", "5-10kb", "10-100kb", ">100kb")

For species with small genomes (e.g. Fruit flies, yeast, C.elegans) these are huge distances and being able to customise them would be fantastic.

Thanks a lot!
