// Description: The process to kill e- to save CPU

// Class description:
//
// G4ElectronCapture allows to remove unwanted e- from simulation in 
// order to improve CPU performance. There are two parameters:
//                 
// 1) low energy threshold for e- kinetic energy (default 0)
// 2) the name of G4Region where process is active
// 
//
// If an electron track is killed then energy deposition is added to the step
