Create API for doing a search with uploaded matchers

[nealeu]

Need to be able to do a query that isn't against something.

This means that we need to be able to do a query by providing a ScoreConfiguration object, and no other profile.

This can then be used in a DSL for creating them as requested in issue #11

[nealeu]

Thinking about the DSL, we want to be able to specify the cutoff as attribute(salary).within(50000).of(500000), such that for 100% score weighting, 550000 would score zero. For matching multi enum, we want something like attribute(newspaper).includes("Guardian", "New York Times")
