/*
* Hyper Tree Api
*
* Hyper tree is the tree view of the rdf store. This is for use by the FE in
* implementing the nav center.
*
* The RDF structure could be a gnarly graph whose nodes are RDF_Resource.
* There can be multiple tree views (HT_View) into this graph. Corresponding
* to each view, there is a hyper tree whose nodes are HT_Resource.
* Each HT_Resource belongs to exactly one HT_View.
* The FE iterate over the hypertree to draw it. It can start the iteration
* either at the top or at some interior node. When some state change occurs
* in the hypertree, the FE will get notified about the node on which the
* change took place. At that point, it can either redraw the whole thing
* or do a partial redraw. The FE does this by iterating over the relevant
* portions of the hypertree. Since the hypertree is a strict tree, the FE
* can also iterate upwards.
*
*
* Possible state changes to the hypertree of an HT_View include :
* (i) addition/deletion of nodes
* (ii) containers closing/opening
* (iii) selection changes
* These changes could occur either because of
* (i) User clicking around the tree
* (ii) Network activity
* (iii) scripts running
* The FE can recieve notifications about these activities.
* If the FE does not want to be notified about something, it can set
* the notification mask to block certain notifications.
