ChangeFolderTask

Summary

Create a new task to apply labels to a message or thread.

Takes an options object of the form:

• folder: The {Folder} or {Folder} IDs to move to
• threads: An array of {Thread}s or {Thread} IDs
• threads: An array of {Message}s or {Message} IDs
• undoData: Since changing the folder is a destructive action, undo tasks need to store the configuration of what folders messages were in. When creating an undo task, we fill this parameter with that configuration
