+            POINTERS AND REFERENCES TO INTERNAL DATA
+                swap() and current() functions do not invalidate pointers or 
+                references to internal data.
+                All other functions have no such guarantee.
+
+            INITIAL VALUE
+                size() == 0    
+
+            ENUMERATION ORDER
+                The enumerator will iterate over the elements in the queue in the
+                same order they would be removed by repeated calls to dequeue().
+                (e.g. current() would be the first element enumerated)
+
+            WHAT THIS OBJECT REPRESENTS
+                This is a first in first out queue containing items of type T
+                
+                e.g. if the queue is {b,c,d,e} and then 'a' is enqueued
+                the queue becomes {a,b,c,d,e} and then calling dequeue takes e out
+                making the queue {a,b,c,d}
+
+                Also note that unless specified otherwise, no member functions
+                of this object throw exceptions.
