Commenting out unused members.

I want to get this commit into the history because
the tests pass here, which demonstrates that every commented
out method is not only unnecessary internally but has zero
test coverage. Since I know (based on the occasional source
code comment, or more often based on knowing something about
other source bases) that some of these can't be removed
without breaking other things, I want to at least record
a snapshot of the identities of all these unused and
untested methods.

This commit will be reverted; then there will be another
commit which removes the subset of these methods which I
believe to be removable. The remainder are in great need of
tests which exercise the interfaces upon which other
repositories depend.
