// Relation declares one WinterCMS attachOne or attachMany relation of an
// Owner model. Name is the relation name stored in system_files.field, Many
// is true for attachMany (false for attachOne), and Public decides the
// is_public flag of files stored through the relation: a protected relation
// (Public false) stores is_public=false rows, for which the framework never
// builds a public URL.
