More boolean Matchers.

Key: LUCY-117

Project: Lucy
Issue Type: New Feature
Components: Core - Search
Reporter: Marvin Humphrey
Assignee: Marvin Humphrey
Priority: Blocker
ANDScorer, NOTScorer, and RequiredOptionalScorer all subclass PolyMatcher,
like ORMatcher/ORScorer.
These three matchers are much simpler to implement than ORMatcher/ORScorer:
ORMatcher.c is longer than the other three .c files combined. OR-combining is
simply much harder to do well when proceeding doc-at-a-time, and the optimized
code in ORMatcher.c takes up more space.
