Use these handy functions to find congessional targets by zip code. AND optionally filter those members by setting:
- A target chamber - e.g. HouseorSenate
- A target party - e.g. DorR
- A list of target senators - either an array of names ["Ted Cruz","Mitch McConnell"], twitter handles["SenTedCruz","McConnellPress"], or Bioguide IDs["B001282","C001098"]
Will return an empty Sunglight API Call { results: [ ], count: 0 }  if there are no results after the filter.
