Detailed Description

The class that represents isotopologues above a given joint probability value.

This class generates subsequent isotopologues that ARE NOT GUARANTEED TO BE ORDERED BY probability. The overal set of isotopologues is guaranteed to surpass a given threshold of probability contained in the isotopic distribution. This calculations are performed in O(N) operations, where N is the total number of the output isotopologues.

This class is not a true generator yet - the generator methods have been implemented for compatibility, but the class actually performs all computations during the initialization and stores them, and the generator methods only walk through the array of precomputed values. . It will be reimplemented as a true generator in 2.0.
