Particle logger
Next step in implementing streaming IO: add a logger
that reads/writes parts
, gparts
, and timestamps to a dump
(following #126 (closed)).
Comes with a nice unit test!
Note that this does not yet touch the rest of the code, so it should have no effect on the rest of SWIFT. The next step will involve implementing a global dump and a new task type that actually writes particles in need of a move.
