3D infinite square well

I think this potential is simple and has an analytic solution.

I can implement this module. The other models in the open issues seem to require numeric solutions.

This is a good first issue (development practice). I would like to save it for the main force developers of Antique.jl v2.0.0. I want you to work on challenging issues if you haven't started developing yet.

The purpose of this package is to provide a benchmark for numerical calculations. There is no problem even if it is not a "pure analytical" solution, as long as it is "almost analytical". The problem is that it will take more time, but I will support you.

How about the model below?

• ground state of Rubber-Band Helium #35 (useful for us, benchmark of three-body calculation)
• Eckart potential #1 (generalization of Pöschl-Teller potential)
• finite well potential (a good example of "almost analytical" solutions)
• Linear Potential with Airy function #17 (a good example of "almost analytical" solutions)

I believe that various potentials can be applied to general 1D, 2D, and 3D problems, including potential wells and their symmetries such as spherical, cylindrical, etc. Perhaps it is interesting to consider.
