[rules-dev] Match vs Activation

[Mark Proctor]

While working on other designs I'm wondering if a better Class name for 
Activation is actually Match.

Once a rule is matched and an Activation is produced, as the Activation 
has fired it remains true. i think I prefer
Match.isActive
to
Activation.isActive

Further Activation is harder to shorten and just looks wierd act vs match.

Also for evens you have onMatch and onUnMatch which I think is nicer for 
saying when a rule becomes true and then becomes untry for a given tuple[].

I know as well Clips uses the term PartialMatch instead of the term 
LeftTuple.

Anyway some whimsical thoughts for the day :)
