Detailed Description

Wrapper class for random number generators used by the simulation classes.

The random numbers are separated two sources of randomness:

• technical random numbers which should represent technical sources of variability like instrument noise and
• biological random numbers which should represent biological sources of variability (e.g. between two samples of the same composition)
