When supplied with a 1-, 2-, 3- or 4-digit year or decade, returns the name of the century.

Mostly used in categorisation.

== Parameters ==
# The first parameter is required: either a 1-, 2-, 3-, or 4-digit year (e.g. 61, 905, 1839) or a 2-, 3-, or 4--digit decade (e.g. 60s, 900s, 1830s)
# The second parameter is optional. The single word "dash" changes the output from "nth century" to "nth-century"
# An optional "nomatch" parameter may be used to specify text to be return if the input cannot be processed.  Default behaviour is return an empty string if there is no match
