0028 // Description: Sets up particle beam
0029 //
0030 //     By default 1 pi+  is shot from (0,0,0)
0031 //     in (1,1,0.1) direction at 100 GeV
0032 //     Use /gun/... commands to modify energy,origin,direction at run time.
0033 //     or/and
0034 //         /CCal/generator/random true/false to have random direction
0035 //         /CCal/generator/scan   true/false to scan in eta/phi
0036 //     Use
0037 //         /CCal/generator/minEnergy
0038 //         /CCal/generator/maxEnergy
0039 //         /CCal/generator/minPhi

0041 //         /CCal/generator/minEta
0042 //         /CCal/generator/maxEta
0043 //     to set the range in energy and direction of particles shot at random.
0044 //     Use
0045 //         /CCal/generator/stepsPhi
0046 //         /CCal/generator/stepsEta
0047 //     to set number of steps in Phi and Eta for the scan
