Generate QuickStatements to add "instance of: placeholder taxon" to items with P28 statements

P28 "representative sequence for placeholder taxon" is intended for placeholder taxa, i.e. items that are described in the literature like taxa or provisional taxa and have a published phylogenetic marker sequence, but where a matching taxon ID in NCBI Taxonomy is not yet assigned.

Generate QuickStatements to link interaction hosts to their genera

Split labels, e.g. "Paramecium caudatum" on whitespace, take the first word as a putative genus name, and look for items with taxon rank "genus" that match the putative genus name. Have to avoid assigning labels like "Cryptotermes symbiont", instead use "symbiont of Cryptotermes" to avoid false matches.

Generate QuickStatements to create items for DOIs found in references without corresponding items
