Subject: [PATCH]  Add function to download pdf and download based the
 downloadBtn parameter

A new taxonomy for the download button should be added in the base configuration file.
eg downloadable = "downloadBtn"
When this downloadBtn is added in the front matter of any of the content files, it will be displayed.
eg downloadBtn: "true"
Adding it to the archetypes and setting it to false by default be awesome.
