Description       : TTM DelayPlots class definition
Language Version  : C++
OSs Tested        : Solaris 2.6

The DelayPlots class groups all data and funtions needed to
create TTM plots for a given source and one or more target boxes.
The interface to the outside is provided by two methods:

  Fill() - processes data and fills ROOT histograms
  Plot() - create plot(s) from the previously filled histograms.
