Situations where a fetch can retun no causal context

Hi Michael,

For the Set, Map, and Counter data types the only other situation I can
think of is if the user explicitly set the "INCLUDE_CONTEXT" option to
false.  That option defaults to true, so it should always return one if the
data type you fetched isn't a bottom (initial) value.  If it is the bottom
value, the context will be NULL.
