Subject: [PATCH 1/3] [ADT] Add more useful methods to SmallSet API

This patch adds useful methods to the SmallSet API:

 - Constructor that takes pair of iterators.
 - Constructor that takes a range.
 - Constructor that takes an initializer list.
 - Copy constructor.
 - Move constructor.
 - Copy assignment operator.
 - Move assignment operator.
