Clemens Hammacher ab350c16a9 Add stream helper to output any iterable collection 
{PrintCollection} can print any collection which is iterable via a
standard for-each loop in C++. The output format of {4, 7, 11} is:
[4, 7, 11]

This helper avoids a few repetitions of manually outputting such
collections.
