+ * WAX - it's a metaphor!
+ *
+ * The WAX framework allows object to have generic/anytype properties.
+ * These properties can be addressed through generic/anytype identifiers.
+ * A property of a WAX object may even be another WAX object.
+ *
+ * When a property is a WAX object, the returned value must be an obj pointer.
+ * A WAX object provides two types of pointers: obj::ptr and obj::sptr.
+ * The choice of pointer vs smart pointer depends on the owner of the memory.
+ *
+ * Proprties may be referenced though the [] overloaded operator.
+ * The [] operator returns a special proxy that allows for assigment.
+ * Also, the [] operators may be chained as in the folowing examples:
+ *   my_obj[prop1][prop2][prop3] = value
+ *   value = my_obj[prop1][prop2][prop3]
+ *
+ * Any value returned from an access operation is of wax::type.
+ * To use this value, it must be cast with wax::cast<new_type>(value).
