Compute incremental random samples from a type frequency list (an

an object of class
a vector of non-negative integers in increasing order, the sample sizes for which incremental samples will be generated
The current implementation is reasonably efficient, but will be rather slow when applied to very large type frequency lists.
N is a single integer (and the

N is a vector of length greater one, or if

tfl objects representing
incremental random samples of the specified sizes N.
Incremental means that each sample is a superset of the
