truth assignments for the atoms of the formula
 we can see how truth values propagate up the tree.

 The formula will be displayed in tree form.
 Assign truth values to the atoms in the formula using the boxes at the

 the truth values.
 Press the "TRUTH VALUE" button to generate a tree displaying the truth
values of operators given your truth
 assignments.
