Implement support for Json serialization

[Jones-Adam]

Provide support so that newtonsoft.json can serialize Spatial types

[Jones-Adam]

145 implements a JsonConverter that can handle all spatial types.

using it is fairly trivial To Serialize:

Point2D p = new Point2D(1,2);
JsonSerializerSettings settings = new JsonSerializerSettings();
settings.Converters.Add(new SpatialJsonConverter());
string jsonString = JsonConvert.SerializeObject(p, settings);

To Deserialize:

JsonSerializerSettings settings = new JsonSerializerSettings();
settings.Converters.Add(new SpatialJsonConverter());
JsonConvert.DeserializeObject(jsonString, settings);

Are there any other use cases to support with json serialization?

@Jones-Adam it's been 1.5 years... Any chances of merging the serialization branch into master and releasing a nuget for it? I'm not sure what's the blocker there, but am willing to contribute.

Hi! I agree, with @Leon99, why has this not been released yet?

[Jones-Adam]

@Leon99 @samirem Releases are handled by @cdrnet for this repository. While the code was feature complete at the time it was written, I would imagine that it should be updated to support the current library versions and maybe add support for MessagePack as well before being merged.

Can we please revive this issue now that #181 has been pushed to master?

[Jones-Adam]

revive away - the sticking point last time was concern the packaging of support for multiple serialization libraries introduced dependencies, even if optional. Let me know how you want it put together and I am happy to update the code to support the latest versions of the libraries

Hi @Jones-Adam , thanks for replying. I managed to fix some bus and create a new v0.7.0 tag, however I have not been able to reach out to @cdrnet; I have no rights neither to publish the nuget package in the name of the Math.NET (NuGet) organisation, nor to update the project website or documentation. 😞

I think the idea that was thrown at #47 , that we offer XML and JSON serialization as separate nugets, is definitely worth investigating.
