// Try to fill field when creating an author page. Fields always filled, are
// lastname, firstname, lastinitial, wikipedia. Birth/Deat year filled iff an
// article is available on wp:en. Try also to avoid duplicate author:
// by creating a redirect if the wikipedia is non empty, its title
// is different from the current Author:title and an Author:new_title
// exists.
