contrib/hxhim_dependencies.sh should be run first in order make sure all dependencies are available. The build_name argument of contrib/hxhim_dependencies.sh is a string that will be appended to download_dir, not a full path. build and $(hostname) are recommended.

• The number of databases must remain the same across all runs for the stored data to make sense.
• All pointers that are passed into HXHIM are still owned by the caller.
• All pointers that come from HXHIM must be freed through their 'hxhim_*_destroy' functions.
