Support multiple surnames & changes for Bertrand
- If authors have multiple surnames, this should be handled as follows: BEFORE the line "Project contributors: FirstName Surname1 Surname2" you have to include another COMMENTED line in the index.rst file as follows: .. Project contributors: FirstName {Surname 1 Surname2}
- the Python scripts are modified accordingly. Note that the script always takes the content of the FIRST appearance of "Project contributors" and "Software used", including uncommented lines.
