Geo Extension

This extension provides geo data related functionality such as checking whether a given geo coordinate is within a predefined geo-fence, etc. Following are the functions of the Geo extension.

Geo Coordinates function

Syntax	`<double, double, string> geocode (<string> location` `)`
Extension Type	StreamProcessor
Description	Transforms a location to its geo-coordinates ( `longitude` and `latitude` ) and formatted address.
Example	`geocode(duplication rd)` returns the following data with adherring latitude, longitude, and `formattedAddress` attribute names respectively. `6.8995244d, 79.8556202d, "R A De Mel Mawatha, Colombo, Sri Lanka"`

Reverse Geocode Stream Function

Syntax	`<object>geo:reversegeocode(<int,long,double,float>latitude, <int,long,double,float>longitude)`
Extension Type	Stream Function Processor
Description	Transforms latitude and longitude coordinates into precise address information.
Parameters	`latitude`: The input location specified in terms of latitude. `longitude`: The input location specified in terms of longitude.
Return	The output object contains an array of string properties including the `streetNumber`, `neighborhood`, `route`, `administrativeAreaLevelTwo`, `administrativeAreaLevelOne`, `country`, `countryCode`, `postalCode` and `formattedAddress` in the given order. However, all this information is not available for all the geo coordinates. For example, if the latitude and longitude represent a place in a forest, only the high level information such as the country is returned. `N/A` is returned for properties for which values cannot be obtained.
Example	`geo:reversegeocode(40.715229, -73.8564082)` returns `{"67-53", "Flushing", "Loubet Street", "Queens County", "New York", "United States", "US", "11375", "67-53 Loubet St, Flushing, NY 11375, USA"}`
