33/**
34 * The public interface to a native stripe object.
35 *
36 * Stripes consist of two properties:
37 *  - they have a unique name by which they can be identified across the network
38 *    In other words: the identity of a stripe is its name
39 *  - they have a list of parent stripes: a stripe is then a 'substripe' of these parents
40 *
41 * Stripes have one important operation: one stripe can be tested to be a substripe of
42 * another stripe.
43 * 
44 * Stripes are very similar to empty Java-like interface types, and their main purpose
45 * lies in the *classification* of objects. AmbientTalk Objects can be striped with zero
46 * or more stripes.
