Analytics graphs

Block that generates graphs intendend to facilitate pedagogical decisions. The graphs have zoom capabilities and allow fast communication with students through email.
This plugin provides five graphs that may facilitate the identification of student profiles. Those graphs allow the teacher to send messagens to users according to their behaviour inside a course. The graphs show:
Grades Chart – The grades distribuition in a box graph to identifiy the differences among evaluations and students with problems.
Content Accesses Chart – Which users accessed many different rsources.
Number of Active Users Chart – How manu users are active in a certain time of day.
Assignment Submissions Chart – Which users have submited assignments on time or late (tasks, quizzes and hotpotatoes).
Hits distribution Chart – How each user is accessing the course and its resources in each cours week.
It is possible to click over graph elements in order to send email to a group of students (first two graphs) or to a particular student (last graph).
