Class for the generation different ions during one simulation.
The ERIonMixGenerator defines the parameters of primary ion and background ions which participates in simulation. It provides interfaces for determining different types of dimentional, angular and energy distributions at beam start position. Also it allows to add background ions with certain probability of appearence. Probability of primary ion is 1. For background ions it normalized relative to the main ion.
