moodle-block_use_stats
======================

This block precompiles time gaps from logs, and arrange gaps into a multiindex data cube for further extractions.

this block can be used alone to display users spent time estimation in owned courses, or get any user
time information for power users.

Usually this block serves as precomplation tool for the much more featured Training Session Report module, that will exploit
compiled gaps for complete learning session time spent information reports.
