UserSets and UserProblems

[pstaabp]

In ww2, we have getMergedSet and getMergedProblem that pulls both the set/problem info and the user-level info and creates the set or problem with the user overrides.

We also have getUserSet and getUserProblem, which just pulls the user set/problem info without the global set/problem info (it appears). Looking through the code, all of the instances where this is used, it appears that getMergeSet and getMergedProblem could have been used instead. It seems this is used when updates to user sets and problems are used.

I'm thinking that for ww3, I would use getUserSet and getUserProblem (and others) that would act like getMergedSet and getMergedProblem and then putUserSet and putUserProblem would just write any user overrides to the db.

Let me know if we feel that having both getMergeSet and getUserSet would be necessary.
