 It demonstrates how to access LAMMPS data as numpy arrays. This gives direct
 access to memory owned by the C++ code, allows easy manipulation through numpy
 operations and avoids unnecessary copies.

 This version of melt example uses NVE_Opt instead of NVE. While this Python
 implementation is still much slower than the native version, it shows that
 simple code transformations can lead to speedups.
