(Taxon addition feature) Adding genera

[jar398]

These situations came up during today's hangout:

Sometimes a set of OTUs will form a new genus. That is, you will want to add a species, and will find that the genus that it goes in doesn't exist yet in OTT.

Sometimes there will be a new genus consisting of a mix of existing and new species (splitting).

Sometimes a genus name X known to OTT will be a synonym of genus Y because it was merged ('lumped') into Y. But a better classification (according to the curator) would be to undo the merge, and re-assert X on its own footing. At this point we reduce to the previous case, since X will consist of a mix of old taxa (currently in Y) and new ones from the study. (e.g. Laverania and Plasmodium, thanks @bredelings)
