Generation of MS fragments

Our motivation to implement a structure generator based on the network principle was the necessity to generate fragments that can occur in a mass spectrometer. Here are the features that we need (see Chapter 8)  

Steps i) and ii) need not be modified. In order to meet the other conditions, we introduce the following extensions  

Since only unimolecular reactions occur, we can restrict attention to row (4) of Algorithm 5.15 while restricting the product formation to Otherwise, Prodjj (IJjgjc. ,) would produce duplicates only. The modified algorithm contains the depths of the reaction schemes as an additional argument
