[LON-CAPA-dev] extracting usage stat

Take a look at lonmeta.pm, the dynamicmeta subroutine.

It is doing a dump of the nohist_resevaldata database with a regexp of
the resource the person is interested in.

It then splits up the returns, you probably shoudl do a get against
the nohist_resevaldata database for the particular item you want. 
The count item is number of accesses, and course is a course using the
the resource.

Right now it is very expensive to get this data, I think we may need
to move to storing this data in one of the mysql caches, probably on
the library server and periodically updating it.

I am not sure what you mean by part type. Parts don't have a type. . .
