 * Abstract encapsulation of the concept of a type's identity. This is particularly useful when you want to use objects of that type in a map or collection, but
 * you want to define the {@link #equals(Object, Object)} and {@link #hashCode(Object)} objects in a way that differs from the type's default. Objects returned
 * from {@link #of(Object)} will wrap values of the specified type T and use the identity methods from this {@link IIdentity}.
