> Currently in streaming expression, if we wanna provide a list of named/unamed parameters.
We wrap the values inside a StreamExpressionValue and manually separate value based on ','
character. 
> In order to make the streaming expression more compact and extendable, I propose new
kind of parameter to streaming expression. 
> {code}
> Map Expression Parameter : { key1 = value1, key2 = value2, .... }
> {code}
> So new tuple stream can be 
> {code}
> arrays({term=a, score=1.0}, {term=b, score=2.0})
> or
> search(collection1, q=*:*, fl="id,a_s,a_i,a_f", sort="a_f asc, a_i asc", aliases={a_i=alias.a_i,
a_s=name})
> {code}
