pub fn create(
kind: Kind,
account: &str,
name: &str,
color: Option<&str>,
components: &[&str],
) -> Result<Collection, String>Expand description
A new collection made here: its folder, its name and colour, and a state
that asks the next sync to create it on the server (MKCALENDAR or an
extended MKCOL). components says what a calendar holds (“VTODO” for a
task list). Returns it; an id already taken gets a number.
