Log Message:
Added generic function to convert arbitrary expressions to indexable tests.
By adding cases to 'predicates.expressionSignature()', you can match a
parsed expression that would ordinarily be converted to a true-false test,
and convert it into an indexed test.  Currently, the generic function only
recognizes 'isinstance()' expressions, but you can extend it to do more
complex matches, and later I plan to add support for 'issubclass' as well.

Also, added 'strategy.default' for easy default methods.
