Changed PastAnswers to use a new table
I've made a first stab at implementing "essay" style answers into webwork.
You use the essay answers by making use of the PGessayanswer.pl macro

You graade the answer by using the ProblemGrader which should appear
automatically in the DetailSetList
Added some missing files.  Oops!
Take $n+1$

Added achievement files to modelCourse in courses.dist
bug fix

(1) This update comments out the line in Logout.pm that transmits
the username to Login.pm if the "Log in Again" button is pressed.
This change is needed to suppress an error message in the Login screen
that would appear if Login.pm is sent a username but no other
credentials.
(2) This update adds documentation to authen_LTI.conf.dist
that was lost when authen_LTI.conf.dist was created, probably
due to an out-of-date version of global.conf having
been used to create authen_LTI.conf.dist.
Fixed database.conf.dist to include correct stuff for past_answer
