Enable simulation of artificial Molecules - Stacked quantum dots

For instructional purposes it would be very interesting to be able to simulate stacked quantum dots even in the simple effective mass model. Issues such as bonding-anti-bonding states and even band formation can be studied. I believe some prototype screen shots exist in the prototype advanced-quantum dot lab, that is not published.

Ideally one should be able to select the buffer material and the material composition of the quantum dots. Also the assuming we look at a vertical quantum dot stack it would be nice to be able to simulate multiple quantum dots and various sizes.

    This will a good addition to the future version. The infrastructure already exists to do such simulations. But I am not sure what kind of constraint we need to put in for the tight binding case (due to computational requirement).
