//
// *** Class AliRsnCut ***
//
// Cut base class: all other cuts inherit from it.
// The 'core' of the class is the method "IsSelected()" which
// must be overloaded by any specific cut implementation.
//
// This class provides some default instruments to check values
// against a reference or an allowed range, in order to permit
// a unique way to execute such kind of checks.
// Moreover, if one checks values and ranges using default methods
// a debug message can be printed on request.
