Exceptions in syd

(Inspired from: http://www.tiwoc.de/blog/2013/12/globally-handling-uncaught-exceptions-and-signals-in-c)

Exception are throw with the following macro: EXCEPTION("My error message in " << filename);

When a function could fail (while accessing a database for example), user can catch the exception and display the message with 'what()', as with standard exceptions. For example: syd::Database * db; try { db = syd::DatabaseManager::GetInstance()->Read(filename); } catch (syd::Exception & e) { LOG(FATAL) << e.what(); }

If the exception is not caught by the user, a standard error message is displayed thank to the segmentation signal handler. Main class is sydException.h.
