I've added some more documentation and clarifying tests to `QGramIndex`, so that the implementation is more clear without looking at the code. I found one small bug: q-grams of value `0` (i.e. `AAA`) wouldn't be filtered by `max_count`. I've added a test that would fail if the `.skip(1)` was still there. The size of the `pos` vector was always `|text|`, but it's sufficient to only allocate memory for the number of unfiltered q-grams. Please verify this. I've added a `text="AAAAA"`, `pattern="AAA"` test that should show that things are still working.
