Hi again,

In combination with the change described in the previous email,
I also introduced the 'port' class (see basix/port.hpp),
which is a simplified replacement for the (not that standard) C++ streams.
In particular, I removed the routines

   ostream& operator << (ostream& out, const C& x)

for our types and replaced them by

   port operator << (const port& out, const C& x)

As a consequence, throughout the project, one will have to replace
occurrences of cout, cerr and cin by mmout, mmerr and mmin.

Sorry for the resulting inconvenience...

Best wishes, --Joris
