/* TODO: the data model is very restrictive for generic use, there should be
 * possible to generate more than one output particles. The simplest solution is
 * to add here other fields and constructors; if number of fields will be
 * excessive for simple models like charge exchange then they won't be stored in
 * persistent storage. Other solution is to move production model data field
 * from base class CexmcProductionModel to its ancestors that can decide
 * themselves which concrete data capacity they require. */
