Blank/empty params

[leemeichin]

Should the gem ignore empty params when no default is supplied? We're doing this manually in Amnesty atm because the assumed default creates a malformed query (passing an empty string to an integer field).

I think so, yes.

I think it should be possible to specify that a param is required (or not). Then if a required param is not set then no results should be returned for the query (regardless of the other parameters). If a parameter is not required (ie. the default) then if that param is not set then it should not be included in the query at all.
