4.2 User's Guide to CGNS examples

The demo directory contains some pyCGNS translation of the User's Guide to CGNS examples. Some of the source code can be found at the end of this manual. The examples are as close as possible to the original examples in fortran, but one can find some slight changes. These changes has been done when we wanted to emphasize a specific Python pattern, or when it was not relevant with pyCGNS.
