Mark Nelson 08a385fc85 #70 Added mobile app support
This allows students to view the activity and download
their certificate. It also allows teachers to view the
list of issued certificates, with the ability to revoke
any.

This is for Moodle Mobile v3.5.0 (not to be confused with
your Moodle site version) and will not work on Mobile
versions earlier than this.

If you are running a Moodle site on version 3.4 or below
you will need to install the local_mobile plugin in order
for this to work.

If you are running a Moodle site on version 3.0 or below
then you will need to upgrade.
