// Conditional return on the nhit value. Returns OKTRUE if the event

// Author: P. G. Jones <p.g.jones@qmul.ac.uk>

// REVISION HISTORY:
//         2013-11-14 : P Jones - new revision, based on CutProc.
//         2018-01-14 : N Barros - Added an option to cut on clean hits. Defaults to false.
//         2018-01-16 : R Lane - adjusted the processor to test all events in an EV event (important if running on simulation)
