// *** Class AliRsnTarget ***
//
// Base class used wherever it is needed to check the class type of
// an object (daughter, mother, event) which could be used for
// cut checking or value computing.
// Since most of these operation are implemented into classes that
// operate on any of such objects, then this class helps in making sure
// that the object being processed corresponds to what is expected.
