/***************************************************************
Title: Set.cpp
Description: Set.cpp implements the functions from the Set.h file. It uses the instance of the Vector class to implement these functions that were
previously implemented in the Vector.cpp file. The functions include checking the size of the set, checking if the set is empty, inserting an element
into the set if it does not exist, removes elements from the set, checks if the element exists, and empties the set.
