Container class defined in namespace
CS52 that has similar behavior to std::vector. The Container will continue to be an integer type and have
all the functionality from A04 plus a default constructor, an overloaded constructor, a copy constructor, and
overloaded operators (e.g. index-of [], assignment = and stream insertion <<).
