Statistics (Graph Stats)

Little graph with visitors statistics
This block allow you to view a little graph in your Moodle 2.x with visitors statistics.
This is the evolution of the Graph_Stats block.
In first page, it shows visitors (unique and multi), with details of user and course count.
In course, it shows visitor to the course only.
People with the coursereport/log:view capacity can see a simple page wich show who was connected today, and a link for the course reports of the day.
You can define :
size
colors
style
number of days to shown
With help of some of you, some translation are already (partially) complete : thanks !
