Implementing print output in seperate files
+) Add an option to write information into standard output or into files,
each of which is created by a process
+) Add a new file for global data (constant, value macro, etc)
+) Do a minor change in how to generate doxygen
Test
+) On Curie, with two modes: only client (connected) and client-server
+) All tests passed, each client prints out its info in a seperate file
