views loader (visual query builder)

instead of manual lua code, ie(??):
https://github.com/foundpatterns/contentdb/blob/66ec7a04ca4b194b35e532ae4f99774c8da110fd/read_document.lua
https://github.com/foundpatterns/contentdb/blob/66ec7a04ca4b194b35e532ae4f99774c8da110fd/walk_documents.lua

go from:

or:

to, roughly, in Speakeasy syntax:
```sql
SELECT
node.title AS node_title,
node.nid AS nid,
node.created AS node_created
FROM
{node} node
WHERE
(( (node.status = '1') AND (node.type IN ('article')) ))
ORDER BY
node_created DESC
LIMIT 10 OFFSET 0
```
