Macro parsit::seq

macro_rules! seq {
    ($pos:ident => $elem:ident, $sep:ident ) => { ... };
    ($pos:ident => $elem:ident,$sep:ident, ) => { ... };
}

Helps to parse a sequence

<rule> ::= el {delim el}

    let p:Parsit<TFQ> = Parsit::new("word,word,word,").unwrap();
    seq!(pos => word, comma ,);
