    Accumulo 3970

    Here's a sketch of what I'm thinking for ACCUMULO-3970. It's by no means ready to be merged,
I just want to send the PR as a starting point for a discussion.
    The idea is to define a new type of iterator, a VisibilityTransformingIterator, which
can be set on a table. The iterator is only active in scan scope and is applied before the
scan authorizations. Concrete subclasses of the VisibilityTransformingIterator receive individual
key-value pairs that are present in the table and, for each pair, produce zero or more extra
representations of that value. How these extra representations are produced will probably
be driven by how an organization wants to anonymize or de-identify its data.

    Fixing my new Property definition. Seems like a CLASSNAME type property can't have a default
value of null
