+// Description: Sets up particle beam
+//
+//     By default 1 pi+  is shot from (0,0,0)
+//     in (1,1,0.1) direction at 100 GeV
+//     Use /gun/... commands to modify energy,origin,direction at run time.
+//     or/and
+//         /CCal/generator/random true/false to have random direction
+//         /CCal/generator/scan   true/false to scan in eta/phi
+//     Use 
+//         /CCal/generator/minEnergy
+//         /CCal/generator/maxEnergy
+//         /CCal/generator/minPhi 
+//         /CCal/generator/maxPhi 
+//         /CCal/generator/minEta
+//         /CCal/generator/maxEta 
+//     to set the range in energy and direction of particles shot at random.
+//     Use 
+//         /CCal/generator/stepsPhi
+//         /CCal/generator/stepsEta
+//     to set number of steps in Phi and Eta for the scan
