// This example performs a framing repair - like operation on a list of lines.
// It pulls frames to their nearest level within a tolerance.
//
// Link to the Swarm App: https://swarm.thorntontomasetti.com/app/5f9985a7dd6d710004c38d73/info
//
// The goal with this example is to demonstrate how to pass lists of values in Inputs (including values with custom attributes set), and how to dig into the results data trees coming back as Outputs.
