At the very least this should be a relative path like `"core/src/main/..."` so that it works on different computers. But even better would be for it to be configurable -- the [latest graph code](https://github.com/mhotan/CityBikeDataExplorer/blob/graph-reader/graph-base/src/main/java/se/kth/csc/moderndb/cbexplorer/DatabasePopulator.java#L25) takes a file path as a command-line argument.

I would also consider the option of agreeing on a standard directory where both importers will look.
