Added a null check to GeoLocation and updated ToString()

[niemyjski]

The ToString() must be in a specific format for lat long of which we know...

Also there is only so much precision you can specify (http://www.geomidpoint.com/latlon.html)

You wouldn't want a number converted to 1.3e6 or 1.12345678901234545666666556 when 8 points of precision gets you to 1/16th of an inch

This LGTM 👍 thanks @niemyjski

I'd like to open the discussion though that our implicit conversions should not throw but return null as per c# guidelines /cc @gmarz @russcam

[niemyjski]

hmm, yeah that's a good point.

[russcam]

Agreed on the implicit conversions returning null instead of throwing; if there is a need for a conversion to throw then it should ideally be explicit but then that runs contrary to the value of the implicit conversion 😄

+1 good call @Mpdreamz
