* Function getTreeView

* @description Similar to menu generation code. It recursively fetches pages according to the sitemap, and generates a ul list with drop handlers defined.
*
* @param pageId The current Page the function is operation on
* @param depth depth of the child list to be fetched at each level. Here it is always -1 to fetch till the last element is reached
* @param rootUri here it is /. Look into Menu documentation for implementation of the same elsewhere.
* @param userId This is just to check the permission.
* @param curdepth Current Depth of the recursion
*
* @return HTML - UL list of the tree structure of pages
