Template Update: License/copyright information and DOI added in the PDFs

As you may have noticed, starting from our Vol. 13, No. 3 issue, we now include the license/copyright information and the DOI of each paper in the published PDF files. This update has also been incorporated in our template. This way the published PDF will carry at all times these additional vital information, which should be rather helpful to readers that view the published PDF following a direct link and/or download and keep local copies of published manuscripts.
