28 // 20100114 M. Kelsey -- Remove G4CascadeMomentum, use G4LorentzVector directly
29 // 20100315 M. Kelsey -- Remove "using" directive and unnecessary #includes.
30 // 20100407 M. Kelsey -- Eliminate return-by-value std::vector<> by creating
31 // three data buffers for particles, momenta, and particle types.
32 // The following functions now return void and are non-const:
33 // ::generateSCMfinalState()
34 // ::generateMomModules() (also remove input vector)
35 // ::generateStrangeChannelPartTypes()
36 // ::generateSCMpionAbsorption()
37 // 20100413 M. Kelsey -- Pass G4CollisionOutput by ref to ::collide(); merge
38 // public vs. private ::collide() functions.
39 // 20100511 M. Kelsey -- Remove G4PionSampler and G4NucleonSampler. Expand
40 // particle-types selector to all modes, not just strangeness.
41 // 20100517 M. Kelsey -- Inherit from common base class, make arrays static
42 // 20100714 M. Kelsey -- Switch to new G4CascadeColliderBase class
43 // 20100726 M. Kelsey -- Move remaining std::vector<> buffers here
44 // 20100804 M. Kelsey -- Add printFinalStateTables() function.
45 // 20110923 M. Kelsey -- Add optional stream& to printFinalStateTables().
46 // 20130129 M. Kelsey -- Add static arrays and interpolators for two-body
47 // angular distributions (addresses MT thread-local issue)
48 // 20130131 D. Wright -- Use new *AngDst classes for gamma-N two-body
49 // 20130220 M. Kelsey -- Replace two-body angular code with new *AngDst classes
50 // 20130221 M. Kelsey -- Move two-body angular dist classes to factory
51 // 20130306 M. Kelsey -- Move printFinalStateTables() to table factory
52 // 20130307 M. Kelsey -- Reverse order of dimensions for rmn array
53 // 20130422 M. Kelsey -- Move kinematics to G4CascadeFinalStateAlgorithm
54 // 20130508 D. Wright -- Add muon capture, with absorption on quasideuterons
55 // 20130620 Address Coverity complaint about missing copy actions
56 // 20130628 Add function to split dibaryon into particle_kinds list
