+// Description:   A Circular buffer designed to handle MIDI input,
+//                but able to store any type of object.  Elements
+//                can be read out of the buffer in two ways. 
+//                (1) from a read pointer which extracts the
+//                elements in order by following the write pointer,
+//                and (2) from an index operator related to the
+//                write pointer's location, for example,
+//                object[0] is the last value written into the
+//                buffer and object[-1] (or object[1]) is the
+//                item written just before that.
