Add ensure(Int, NumRange) #488

[antonio-pedro99]

Not really sure what to do with ranges that does not include an end. But my assumption is if a range spans to infinity and the first element in the range is less than n, we should return the first element otherwise return the n.

If n is between beginning of the range and end of the range, the result should be n. If range spans to infinity and the first element in the range is less than n it means that n is in the range.

I guess a good start of the function would be something like n in r returns n
