Make interface more declarative

[jrf0110]

Originally, mongo-pg and mongo-sql we're the same libraries. Mongo-Sql resembles the early muck of the imperative style:

find($query, options)

But this is no longer really needed. This is just a sql generator for JSON. Let's move to this syntax:

{
  type: 'select'

, columns: [ '*', 'extension.field1', 'extension.field2' ]

, tables: [ 'users', 'extension' ]

, joins: {
    leftJoin: { 
      extension: { id: 'extension.id' }
    }
  }

, where: {
    name: { $ilike: 'bob', $or: { $ilike: 'alice' } }
  , id: {
      $nin: {
        type: 'select'
      , columns: 'id'
      , table: 'otherUsers'
      , where: { someCondition: true }
      }
    }
  }

, limit: 100

, order: { id: 'desc' }

, groupBy: ['id', 'name']
}

Where each top-level property corresponds with a field in the base query:

select {fields} from {collections} {joins} {where} {limit} {order} {groupBy}

And each field also corresponds to a builder function.

In this way, you would be able to write custom query types more easily.

Working on helper interface for building custom query types:

var builder = require('this_library_name');

builder.registerQueryType(
  'select products'
, 'select * from products {where} {limit} order by name desc'
);

builder.sql({
  type: 'select products'
, where: {
    name: { $ilike: 'Product Na' }
  }
, limit: 30
, offset: 60
});
