To Do (at least in Uwe's opinion):
======

1. disco must go into klaR and to CRAN!
   (e.g. for partimat)

stepclass:
- LATER: many rather long functions defined in stepclass()
  should be defined in the top level of the package
  (e.g. documenting them as "internal")
- LATER: Rewrite it to be readable.
- allow for *arbitrary* performance measures
- allow for arbitrary predict functions

rda:
- In Main Procedure some loops within loops within ... with
  really bad memory allocatoion as in: new <- c(new, ......)
  e.g. lines 383 ff., the same with calls to cbind()
- LATER: rda.default() - Many functions defined therein rather
  than in the package itself. Why?
- LATER: another optimizer, e.g. optim()?

quadplot:
- rgl implementation

triplot/quadplot:
- check whether membership values are in [0,1]
