Why `select` and `selectAll` wants non-empty seq?
Hello, was trying to use norm for the first time, was reading documentation and it was very unclear for me:

Why the select requires one element in seq? I suppose model (table and etc) goes from type, why the element is needed here?
```
var customersFoo = @[newCustomer()]
dbConn.select(customersFoo, "User.email = ?", "foo@foo.foo")

echo()
```
