used Bio::EnsEMBL::Utils::Exception
Now includes the loading of generic and species-specfic analyses (if configured)
Introduced new category of species: provisional (i.e. things that are allowed, but will not be FTP dumped)
Added Hcontortus_gasser
Now updates the analysis table to set the within-species and between-species parameters correctly
Analysis table is now set up by worm_lite (so removed it from update_dna here)
