resovled build errors but FIX TREETRAVERSAL.JAVA AND TREERANDOMNODE.JAVA ! They were missing methods and made the build fail. Looks like that part isnt finished yet. Just added standard methods to solve build errors ! Class Node already exists, Class TreeNode already exists so i just refactored the one in Treetraversal.java to "NodeTree".
