The documentation about Persistent Storage - Output Files it is not correct since function createContainer do not exist when you load rAzureBatch.

https://github.com/Azure/doAzureParallel/blob/master/docs/72-persistent-storage.md

> createContainer(outputFolder)
Error in createContainer(outputFolder) : 
  could not find function "createContainer"
> rAzureBatch::createContainer(outputFolder)
Error: 'createContainer' is not an exported object from 'namespace:rAzureBatch'
> 

Also added in here: Azure/rAzureBatch#57
