CopyFolder Method
Copies a folder.
Syntax
public func copyFolder(id: String, destFolderID: String) throws -> Void
Remarks
This method copies a folder to a new parent folder. Please note that two folders with the same name may not exist under the same parent folder. Since this method does not change the name of a folder, it is not possible to directly create a copy of a folder in the original folder's location.
