bookshelf.raw.safe
==================

Bookshelf raw extensions to handle things in a safe manner

The idea is to pass error handling up the chain to express, and to always be returning (bluebird)
promises.

``
var safeBookShelf = require('bookshelf.raw.safe')(loggerOfYourChoice);
var safeQuery = safeBookShelf.safeQuery;

db = bookshelf instance / connection

var callingFnName = 'getAll';
var getAll = function(){
safeQuery(db, sqlString, next, callingFnName);
};
