Represent a delete statement

let mut issues = Issues::new(sql);
let mut stmts = parse_statements(sql, &mut issues, &options);

let delete: Delete = match stmts.pop() {
    Some(Statement::Delete(d)) => d,
    _ => panic!("We should get a delete statement")
};

assert!(delete.tables[0].identifier.as_str() == "t1");
println!("{:#?}", delete.where_);

let sql = "DELETE `t1` FROM `t1` LEFT JOIN `t2` ON `t1`.`t2_id`=`t2`.`id` WHERE `t2`.`key`='my_key';";

let mut stmts = parse_statements(sql, &mut issues, &options);
