Data-Objects #1

Everything can be stored in a single set/list of property-value pairs. They have to contain additional non-value entries for objects to keep their type information. Those are stored as 'hidden' using property names starting with a . (which will not be allowed for names of normal properties). Beside the type of the object a path represents they will also contain the count of members. The sorting of the pairs will be in a way that this object identifier property is the first property followed by all its members (and their sub-values). So when this count is known, the object can be stripped out of a more complex one by simply find the object-identifier entry, read it length and construct a new data-object with the new path, start and end for binary search in that object.
