 This is a version of the melt example which replaces the default NVE integrator
 with a Python implementation. Fix python/move is used to create an
 instance of the py_nve.NVE class which implements the required interface.

 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.
