### Logger
In SWIFT, we developed a new way of writing the information contained in
snapshots (Hausammann and Gonnet (in prep.)).
In cosmological simulations, the time scale of the different particles
can differ by a few order of magnitudes.
This technique reduces the data entropy by writing the particles according
to their own time scale.
SWIFT is able this way to increase the time resolution of the output while
keeping the files to a decent size.
