Laoding HCI data is not guaranteed to work properly outside of Idiap
I had to modify the COHFACE Interface, such that it does not rely on Idiap's DB default location (i.e. you can now specify the DB dir where you can load the objects from). The same should be done and tested with HCI, but it will require a bit of resources since the DB is ~310Gb (hence impossible to copy to my laptop for instance)
