 28 // Description: Sets up particle beam
 29 //
 30 //     By default 1 pi+  is shot from (0,0,0)
 31 //     in (1,1,0.1) direction at 100 GeV
 32 //     Use /gun/... commands to modify energy,origin,direction at run time.
 33 //     or/and
 34 //         /CCal/generator/random true/false to have random direction
 35 //         /CCal/generator/scan   true/false to scan in eta/phi
 36 //     Use 
 37 //         /CCal/generator/minEnergy
 38 //         /CCal/generator/maxEnergy
 39 //         /CCal/generator/minPhi 
 40 //         /CCal/generator/maxPhi 
 41 //         /CCal/generator/minEta
 42 //         /CCal/generator/maxEta 
 43 //     to set the range in energy and direction of particles shot at random.
 44 //     Use 
 45 //         /CCal/generator/stepsPhi
 46 //         /CCal/generator/stepsEta
 47 //     to set number of steps in Phi and Eta for the scan
