// 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.
