+// CLASS PROVIDED: bag (part of the namespace main_savitch_3)
+//
+// TYPEDEF and MEMBER CONSTANTS for the bag class:
+// typedef ____ value_type
+// bag::value_type is the data type of the items in the bag. It may be any
+// of the C++ built-in types (int, char, etc.), or a class with a default
+// constructor, an assignment operator, and operators to
+// test for equality (x == y) and non-equality (x != y).
+//
+// typedef ____ size_type
+// bag::size_type is the data type of any variable that keeps track of how
+// many items are in a bag.
+//
+// static const size_type CAPACITY = _____
+// bag::CAPACITY is the maximum number of items that a bag can hold.
+//
+// CONSTRUCTOR for the bag class:
+// bag( )
+// Postcondition: The bag has been initialized as an empty bag.
+//
+// MODIFICATION MEMBER FUNCTIONS for the bag class:
+// size_type erase(const value_type& target);
+// Postcondition: All copies of target have been removed from the bag.
+// The return value is the number of copies removed (which could be zero).
+//
+// void erase_one(const value_type& target)
+// Postcondition: If target was in the bag, then one copy has been removed;
+// otherwise the bag is unchanged. A true return value indicates that one
+// copy was removed; false indicates that nothing was removed.
+//
+// void insert(const value_type& entry)
+// Precondition: size( ) < CAPACITY.
+// Postcondition: A new copy of entry has been added to the bag.
+//
+// void operator +=(const bag& addend)
+// Precondition: size( ) + addend.size( ) <= CAPACITY.
+// Postcondition: Each item in addend has been added to this bag.
+//
+// CONSTANT MEMBER FUNCTIONS for the bag class:
+// size_type size( ) const
+// Postcondition: The return value is the total number of items in the bag.
+//
+// size_type count(const value_type& target) const
+// Postcondition: The return value is number of times target is in the bag.
+//
+// NONMEMBER FUNCTIONS for the bag class:
+// bag operator +(const bag& b1, const bag& b2)
+// Precondition: b1.size( ) + b2.size( ) <= bag::CAPACITY.
+// Postcondition: The bag returned is the union of b1 and b2.
+//
+// VALUE SEMANTICS for the bag class:
+// Assignments and the copy constructor may be used with bag objects.
