```
    constructs a new DistEmpirical distribution.
    
    Parameters:
    
    stream - StreamInterface; the stream to use
    
    empiricalDistribution - EmpiricalDistributionInterface; the cumulative distribution to use
    
    Throws:
    
    IllegalArgumentException - when the empirical distribution has non-integer values
