+/*
+   This example shows how to convert a class from and to native
+   Python objects, such as tuples.
+
+   We do not want to expose the helper class MillerIndex as an
+   Extension Class. However, in order to simplify the wrapper code,
+   we want to define from_python() and to_python() functions for
+   class MillerIndex.
+
+   Consider the alternatives:
+
+     - Expose MillerIndex as an Extension Class.
+         We need a constructor MillerIndex(python::tuple).
+         Python function calls become more complex:
+           foo(MillerIndex((1,2,3)) instead of foo((1,2,3))
+         We need a method such as MillerIndex().as_tuple().
+
+     - Define a wrapper function for each function that we
+       want to expose, e.g.:
+          void add(const IndexingSet& ixset, const python::tuple PyMIx)
+
+   The first alternative introduces a new type that the user has to
+   deal with. Other modules using Miller indices might organize them in
+   different ways, for example to increase runtime efficiency for
+   important procedures. This means, the user has to know how to
+   convert between the different kinds of Miller index representations.
+   This can quickly become a nuisance. Relying on native Python data
+   structures minimizes the number of special types the user has to
+   learn and convert. Of course, this argument is only valid for
+   small and relatively simply classes.
+
+   If there are many member functions with MillerIndex arguments, the
+   second alternative is impractical, and concentrating the conversion
+   mechanism in one central place is essential for code
+   maintainability.  An added benefit is that more convenient (smarter)
+   conversion functions can be provided without cluttering the rest of
+   the wrapper code.
