Attached the initial impl as a Java class. I'll post a patch after I do some cleanup on my local master branch.

> The random Streaming Expression will return a *limited* random stream of Tuples that match a query. This will be useful in many different scenarios where random data sets are needed.
> Proposed syntax:
> {code}
> random(baskets, q="productID:productX", rows="100", fl="basketID") 
> {code}
> The sample code above will query the *baskets* collection and return 100 random *basketID's* where the productID is productX.
> The underlying implementation will rely on Solr's random field type.
