Computes the intersection of this bag with another bag. The intersection of two bags
is all items that appear in both of the bags. If an item appears X times in one bag,
and Y times in the other bag, the intersection contains the item Minimum(X,Y) times. A new bag is
created with the intersection of the bags and is returned. This bag and the other bag
are unchanged.

Parameters
- otherBag
- Bag<(Of <T>)>
Bag to intersection with.
Return Value
The intersection of the two bags.Remarks
When equal items appear in both bags, the intersection will include an arbitrary choice of one of the two equal items.
The intersection of two bags is computed in time O(N), where N is the size of the smaller bag.
