Added the EAGLE 6Mpc box Initial conditions example

examples/EAGLE_ICs/EAGLE_6/README

+Initial conditions corresponding to the 6.25 Mpc volume
+of the EAGLE suite. The ICs only contain DM particles. The
+gas particles will be generated in SWIFT.
+
+Note that this is a very very small volume. It will not result
+in a galaxy population matching the data averaged on large scale.
