Enrolment audit

This plugin enables tracking the history of learner enrolments at site and course level.
How does it work?
Following installation, the plugin will go over all of the historic learner enrolment data available in the database to populate the initial report data.
After that, the plugin has an observer setup to watch for the events
user_enrolment_created
user_enrolment_updated
user_enrolment_deleted
All data that is relevant to the report gets stored in a new DB table  report_enrolaudit . This lets us take a snapshot of the user enrolment, as Moodle does not provide information on what changes in an enrolment update, neither in the log tables or in the enrolment events.
