	r2 := rope.New("test rope")

Concatenate two ropes

	r1 := rope.New("abc")
	r2 := rope.New("def")
	
	r3 := r1.Concat(r2) // "abcdef"

Split a rope

	r1 := rope.New("abcdef")
	
	r2, r3 := r1.Split(4) // "abcd", "ef"

Delete from a rope

	r1 := rope.New("abcdef")
	
	r2 := r1.Delete(3, 2) // "abef"

Insert in a rope

	r1 := rope.New("abcdef")
	
	r2 := r1.Insert(3, "xxx") // "abcxxxdef"

Rope substring

	r1 := rope.New("abcdef")
