[WWdevel] more logging

[John J. <jj...@as...>]

Webwork 1 had a fuller logging procedure, where basically every click 
was logged.  I found that useful since I sometimes had to figure out 
what a teacher had done (in addition to answering questions about what 
students did).

The webwork 2 logging framework made it easy to replicate this: one line 
in global.conf to define the log file, and then one (long) line in 
ContentGenerator to call the writeCourseLog to record the url and the 
cgi parameters.  So, this raised a couple of questions:

    * would we want this facility in the main webwork?
    * if so, should it be more refined (so individual modules can give
      more finely tuned log entries)?

Thoughts?
