Added first version of cut monitoring + style format applied

//
// This cut selects the AliRsnDaughter objects pointing
// to tracks with a well defined true particle species,
// defined through its PDG code or species according the
// enumeration defined in AliRsnDaughter class.
// ---
// Using this cut on data results in no tracks passing it.
