Can we use ~/.aws/credentials file?

[Aaron Baker]

If you use the plain aws-sdk you can init the DynamoDB object like:

var db = new AWS.DynamoDB();

This pulls the access key and secret from a file in ~/.aws/credentials.  Can this plugin be initialized the same way? i.e.

var dynamodb = require('dynamodb').ddb()

refers to the credentials file if no arguements are passed?  Currently I get an error when I try to do this.
