+=head1 DESCRIPTION
+
+ Checks if there is an analysis named alphafold_import with at least one
+ associated protein_feature.
+ Checks if all features have a hit_name like AF-\w+-F\d+ (matching e.g.
+ AF-A0A2I1PIX0-F1).
+ Will only run once per multispecies (collection) DB, since an Alphafold
+ analysis is not per species, but per schema.
