/*
* The rough working of the Model -
*
* Each file/subdir/dir is a #_Node.
* There are 2 types of #_Node - a file #_Node & a dummy Node.
* A file #_Node is one which could also be a subdir. But the key
* differentiating factor is that a file #_Node is always initialized with a file
* while a dummy Node is initialed with NULL.
* The dummy node's main purpose is to act as a child for a subdir
* which has not been expanded in the view yet.
* Whenever a #_Node is loaded, the node's file's children will be added as
* child nodes. If any of these child nodes are non-empty directories then
* they will additionally be given a dummy child node. When these subdirs
* will be loaded (expanded in the view), the dummy child node will be replaced
* by the actual children of the node.
*
* A Node's children are stored in sorted manner in a GSequence and additionally
* a HashTable is used to quickly query and retrieve the required child.
