Geocoding API's

[mattleibow]

A simple way to convert from a position to an address.

Geolocation API's: #7

_NOTE: the Position type is used from #7 _

static class Geocoding {
    // Requires a map key string on UWP
    // should throw an exception on UWP if this isn’t specified via the static MapKey property.
    static Task<IEnumerable<Address>> GetAddressesAsync(Position position);
    static Task<IEnumerable<Position>> GetPositionsForAddressAsync(string address);
}

// UWP-only partial
static class Geocoding {
    // UWP Only, and should only be in the UWP assembly
    // Users can call `Geolocation.MapKey = "blah"` from their UWP specific code (like where Inits are called).
    static string MapKey { get; set; }
}

class Address{
    double Latitude { get; set; }
    double Longitude { get; set; }

    string AdminArea { get; set; }
    string CountryCode { get; set; }
    string CountryName { get; set; }
    string FeatureName { get; set; }
    string Locality { get; set; }
    string PostalCode { get; set; }
    string SubAdminArea { get; set; }
    string SubLocality { get; set; }
    string SubThoroughfare { get; set; }
    string Thoroughfare { get; set; }
}

Also should add:

Task<IEnumerable<Position>> GetPositionsForAddressAsync(string address);

Also required MapKey on UWP.

I'll take this as I personally implemented it in my plugin
