/****************************************************************************
*
* FUNCTION: FillTreeView( LPSHELLFOLDER lpsf,
* LPITEMIDLIST lpifq,
* HTREEITEM hParent)
*
* PURPOSE: Fills a branch of the TreeView control. Given the
* shell folder, enumerate the subitems of this folder,
* and add the appropriate items to the tree.
*
* PARAMETERS:
* lpsf - Pointer to shell folder that we want to enumerate items
* lpifq - Fully qualified item id list to the item that we are enumerating
* items for. In other words, this is the PIDL to the item
* identified by the lpsf parameter.
* hParent - Parent node
*
* COMMENTS:
* This function enumerates the items in the folder identifed by lpsf.
* Note that since we are filling the left hand pane, we will only add
* items that are folders and/or have sub-folders. We *could* put all
* items in here if we wanted, but that's not the intent.
