Size K Subset Generator
Produces all subsets of a given set.
The SizeKSubset class is meant to be used by another class that will provide a suitable set of data and invoke the appropriate iterator methods.
The SizeKSbuset class does have a stub Main method that will generate some sample data for a set of size n = 10, consisting of the integers from 0 to 9, with a subset size of k = 5.
There is some commented-out code in the Main method that can be used to explore some edge cases.
