   * The **ClassImp(ana)** and the **ClassDef(ana, 1)** are necessary for the full functionality. ana names the class and the number in **ClassDef** is the VersionID; it has to be greater than zero. **ClassDef(...)** always has to be the last statement before the closing bracket. These statements are needed to create the dictionary for ROOT in the compilation process.   * The **ClassImp(ana)** and the **ClassDef(ana, 1)** are necessary for the full functionality. ana names the class and the number in **ClassDef** is the VersionID; it has to be greater than zero. **ClassDef(...)** always has to be the last statement before the closing bracket.
