//! Header file for the Wire_Chamber sensitive detector class.

//! The WC_SD class defines the member functions for processing the hit
//! information whenever a hit is simulated in the detector.  These
//! routines initialise the hit collection, process hits, and perform
//! the end of event action which writes out the hit information.
