option.

Notes:* Using EventArgs allows us to extend arguments without
changing event signatures.
requirement for that to happen. although outside of
'empty' this is a somewhat useless class :)
Purpose: A single instance of this class so that we don't have
to pass nulls around (ie we can depend on there always being
a value if we so desire).
