\title{Get KEGG ID}
\description{
  Get KEGGID from a \code{\link{KEGGNode-class}} object.

  The \code{\link{KEGGNode-class}} can be either another pathway (KEGGID
  in the form like 'hsa\\d*'), KEGG Gene ('hsa:\\d*') or compound
  ('cpd:C\\d*'). In case of the KEGG Gene ID, the organism prefix is
  removed when the value is returned.
