    2727//   MDataChain
     28//
     29// With this chain you can concatenate simple mathematical operations on
     30// members of mars containers.
     31//
     32// In the constructor you can give rule, like
     33//   "HillasSource.fDist / MHillas.fLength"
     34// Where MHillas/HillasSource is the name of the parameter container in
     35// the parameter list and fDist/fLength is the name of the data members
     36// in the containers. The result will be fDist divided by fLength.
     37//
     38// You can also use brackets:
     39//   "HillasDource.fDist / (MHillas.fLength + MHillas.fWidth)"
     40//
     41// The allowed operations are: +, -, *, /
     42//
     43// Warning: There is no priority rule build in. So better use brackets
     44//   to get correct results. The rule is parsed/evaluated from the left
     45//   to the right, which means:
     46//
     47//   "MHillas.fWidth + MHillas.fLength / HillasSource.fDist"
     48//
     49//    is parses as
     50//
     51//   "(MHillas.fWidth + MHillas.fLength) / HillasSource.fDist"
     52//
     53//
     54// FIXME: The possibility to use other objects inheriting from MData
     55//        is missing.
     56//        Maybe we can use gInterpreter->Calc("") for this.
     57//        gROOT->ProcessLineFast("line");
