 * Create metadata instance on folder

 * Applies an instance of a metadata template to a folder.

In most cases only values that are present in the metadata template

will be accepted, except for the `global.properties` template which accepts

any key-value pair.

To display the metadata template in the Box web app the enterprise needs to be

configured to enable **Cascading Folder Level Metadata** for the user in the

admin console.
