Rename fix python/move to move/python

examples/python/README.fix_python_move → examples/python/README.fix_move_python

 This folder contains several LAMMPS input scripts and a python module
-file py_nve.py to demonstrate the use of the fix style python/move
+file py_nve.py to demonstrate the use of the fix style move/python
 to reimplement NVE using Python.
 
-in.fix_python_nve_melt:
+in.fix_move_python_nve_melt:
 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
+with a Python implementation. Fix move/python is used to create an
 instance of the py_nve.NVE class which implements the required interface.
 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.
 
-in.fix_python_nve_melt_opt:
+in.fix_move_python_nve_melt_opt:
 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.
