 * Post Review Changes By: Justin Basilico
 * Changes Date: May 16, 2006
 * Change Comments: While this interface defines no "functionality" in terms of
 * adding methods, it does define a certain type of object, which is the
 * purpose of an interface. Here it is defining a specific type of function
 * that maps from and to Vectors. This type of function is used extensively in
 * the learning packages, which requires the need for the additional interface.
 * It also makes it easy for us to add functions to this type later on if it is
 * required.
