3e97a3630d Include nascent curator scaffolding. 
The curator doesn't do anything yet; rather, this is the type
definition including the anciliary testing scaffold.

Improve Makefile and Git developer experience.

The top-level Makefile was a bit overloaded in terms of generation of
assets and their management.  This has been offloaded into separate
Makefiles.

The Git developer experience sucked due to lack of .gitignore
policies.

Also: Fix faulty skiplist naming from old merge.

b2e4c88b80 Wrap LevelDB iterator operations behind interface. 
The LevelDB storage types return an interface type now that wraps
around the underlying iterator.  This both enhances testability but
improves upon, in my opinion, the interface design for the LevelDB
iterator.

Secondarily, the resource reaping behaviors for the LevelDB iterators
have been improved by dropping the externalized io.Closer object.

Finally, the iterator provisioning methods provide the option for
indicating whether one wants a snapshotted iterator or not.

f2a30cf20c Several important cleanups and deprecations. 
EachFunc is deprecated.

Remove deprecated ``Pair`` and ``GetAll``.

These were originally used for forensic and the old gorest impl.
Nothing today in the user-facing path nor the tests uses them,
especially since the advent of the ForEach protocol in the
interface.

ceb6611957 Fix regression in subsequent range op. compactions. 
We have an anomaly whereby subsequent range operations fail to be
compacted into one single range operation.  This fixes such
behavior.
