A couple of bits people might find useful to look at/have handy for the 
dataflow telephone meeting of Dec 4th. They probably won't make much sense now
but hopefully all will be clear when I'm speaking.

Sample detector map text file.

# file: emc1.map
  Section: 0 0        # mapping of detector sections to platform elements

       Chip: 0        # chip for section 0
      
      Channel: 0-23   # channels belonging to chip 0 of section 0

  Section: 1 
           1    # can split lines if you want

       Chip: 0
     
      Channel: 0, 1, 2, 3, 4, 5-18,
               19-23          # can write horrible looking things if you want

  Section: 2 2

       Chip: 0
     
      Channel: 0-23




Code to print out the detector and platform addresses of all channels 

  // instantiate a browser
  odfMapBrowser browser(theMap);

  do {
    // go down to the leaf nodes
    browser.bottom();
    
    unsigned int dAdr;
    unsigned int pAdr;
    o << "At level " << browser.currentLevel() << endl;
    while(dAdr=browser.dAdr(), pAdr=browser.pAdr(), browser.next()) {

      if (pAdr==0) 
        o << "platform address out of range";
      else {
        o << "pAdr="; 
        odfpAdr::instance().print(pAdr);
      }

      if (dAdr==0) 
        o << "detector address out of range";
      else {
        o << "dAdr="; 
        odfdAdr::instance().print(dAdr);
      }
      o << endl;
    }
    // find the next branch of the map if there is one.
  } while (browser.nextBranch());
