HashSet<T> Constructor (IEqualityComparer<T>)
Initializes a new instance of the HashSet<T> class that is empty and uses the specified equality comparer for the set type.
The capacity of a HashSet<T> object is the number of elements that the object can hold. A HashSet<T> object's capacity automatically increases as elements are added to the object.
This constructor is an O(1) operation.
