#####Simple local file JSON storage
Saves to settings.json by default. Single function getset(k, v). Asynchronous.

var simpledb = require('./quick.js')();

// Set value - saves to JSON file
simpledb.getset('key', 'value', function(o){
   console.log(o);
});

// Get value
simpledb.getset('key', function(s){
   console.log(s);  // 'value'
});

Alternate file name..

var simpledb = require('./quick.js')('./mydb.json');
