Rebased to current master. This became necessary because the code for `tripleToInternalRepresentation` moved from `src/index/Index.cpp` to `src/index/IndexImpl` and also changed slightly.

Fixed since #962 (the correct query now uses `STR(?statement)` and the result of the `STR` does not contain the `` anymore).

Closing this because the user did not report back.

For over half a year now, SPARQL queries are parsed via ANTLR and there are proper error messages when GROUP BY is used wrongly.

This has been fixed a while ago

This has been done and it was indeed a milestone for QLever.

This was more an observation. Yes, some queries are very expensive, and QLever imposes a memory limit and there will be an error message when that limit is exceeded by...
