leaves(LeafTree) -- list the leaves of a tree

Function: leaves
Usage:

leaves T
Inputs:
- T, an instance of the type LeafTree,
Outputs:
- a set, the leaves of T

Description

This function outputs the leaves of the tree as an object of class Set.

i1 : T = leafTree(4,{{0,1}});

i2 : vertices T

o2 = {set {set {2}, set {0, 1}, set {3}}, set {set {0, 1, 2}}, set {set {0,
     ------------------------------------------------------------------------
     1, 3}}, set {set {2, 3}, set {0}, set {1}}, set {set {0, 2, 3}}, set
     ------------------------------------------------------------------------
     {set {1, 2, 3}}}

o2 : List

i3 : #(vertices T)

o3 = 6

Caveat

The leaves have a different representation from the one in the output of vertices(LeafTree).
