Exploring Predictive Time Series

Hi guys, 

I was checking out Example of Predictive Time Series. There are nodes that i am not able to find it out, like the "Prepare Data"  what node is that? where can i drag it in and use?

I have attached a screenshot here. 

 

Hi Jim,

this is a metanode. Which is a  container for a small subworkflow. You can open it by double clicking to see the content.
