title: Check if coordinates lie in a region
body: <p>If I have a (latitude,longitude) pair, is there a way to determine whether it lies in a 'region'. By region I mean the 'highlighted' result of an query in google maps. For example, when I search for Manhattan, a red region is highlighted. Does Google/Bing provide an API to query if a given coordinate lie in such a region? 
  I am aware of the containsLocation API call that tells me if a coordinate lies in a polynomial already defined as a set of coordinates. The problem here is me not having all the coordinates that can define Delhi</p>
