// This class just stores an int and a float. While not needed it is

// better in the long run to get used to use methods to get to the

// data. It doesn't matter for the root TTree which is saved but if

// you save this class inside a TClonesArray (the other example) it

// makes it easier. It also allows greater flexibility, e.g. if you ever

// want to ("dammit I forgot to multiply myfloat with Pi") modify the

// values on the fly:

// exchange

//  float MyFloat() const {return myfloat;}

// by

//  float MyFloat() const {return myfloat*M_PI;}

// and you don't have to change your analysis code one bit
