Gigasecond exercise cannot load/ignore stub file

[Bajger]

When fetching new exercise Gigasecond in Pharo, there is a problem loading stub solution file:

Reason:
This is probably injection, since stub solution file is no longer empty file, but contains some samples in comments. Pharo parser is rather strict and expects to parse type, which is not there (only comments are there).

Actual
Parser parsing stub file containing just comments fails.

Expected behavior
Parsing via Tonel reader should ignore file containing just comments and skip it.
