### Huckel Determinant Solver

After initializing the determinant for the number of carbon atoms, click on
a determinant element to toggle between 1s and 0s until it is
correct for your compound. A 1 indicates that the two carbons are adjacent; a 0 indicates that the two carbons are not adjacent.
Then click on "Solve" to see all of the roots of the equation. (The default is for linear conjugation.)
