8.7 Snapshot Input

The code for snapshot input is straightforward:

Note that we do not check here whether a complete snapshot is being offered on the standard input stream in the right format. It would be better to verify, for example, that new lines
n occur in the correct places, separating each particle, and that no end-of-file condition is encountered before the whole $N$-body snapshot is read in. In later versions we will provide more complete error checking.
