Implementation of species described by year category. Note: There's a little bit of discrepancy in the categorization scheme here; the categories for 1800, for example, are included in the "1800s" category, which is a subcat of the 19th century cat, even though the 19th century doesn't begin until 1801.

E.g.
Category:Species by year of formal description
 * Category:Plants by year of formal description
 * Category:Plants described in the 18th century
 * Category:Plants described in the 1750s
 * Category:Plants described in 1753
 * Category:Species described in the 18th century
 * Category:Species described in the 1750s
 * Category:Species described in 1753
 * Category:Plants described in 1753
