/******************** insertT ****************************************
 NodeT *insertT(NodeT **pp, Element element)
 Purpose: Inserts into the quote tree at the requested location using double
          pointer notation. If location is NULL, allocates memory.

 Parameters:
 I/O     NodeT **pp              Pointer to a pointer of the location to be inserted
 I       Element element         Item to be inserted into the tree

 Returns:
 pp        Returns a pointer to the node's new position

 Notes:
