there is repeated information on the page

Writing Geospatial Views : the intro paragraph has a lot of dub information. we should simplfy to the following text.

"Geospatial Views adds two-dimensional spatial index support to Couchbase. Spatial support enables you to record geometry data into the bucket and then perform queries which return information based on whether the recorded geometries existing within a given two-dimensional range such as a bounding box. This can be used in spatial queries and in particular geolocationary queries where you want to find entries based on your location or region."
