Example simulations of polarizable systems using Drude oscillators

Each example comes in two versions for demonstrating the use of Nosé-Hoover or Langevin thermostats.

• butane -- simulation in NVT ensemble with Thole damping

• toluene -- simulation in NVT ensemble with Thole damping and

use of the extra/special/per/atom keyword

• ethanol -- simulation in NpT ensemble with Thole damping

• swm4-ndp -- 4-site rigid water model in NpT ensemble (no Thole

damping)
