Create Bundle URL

Create a public access URL for a bundle of items, including forms, assets, documents, and a site check-in.

The following set of "public_access_item" types are supported:

• "form", "id" - this is the ID of the form template
• "document", "id" - this is the ID of the specific document
• "asset", "id" - this is the ID of the asset
• "title", "url" - for a link; we have to specify the title and URL
• "on_site_log" - for the on_site_log the site has to be specified

This generates a link that will encode the bundle.
