Refactor library to support multiple drivers.

[spudwebb]

I created a JsonConverter called ZWJSSJsonConverter so that the Controller, ZWaveNode and Endpoint classes are automatically instantiated with a driver property when deserialized from JSON.

I made all the other changes you listed in #61 (comment)

I successfully tested the library in client mode with 2 drivers.

For the self-hosted mode, I guess it will need some additional changes because in Server.Start() the first thing it does is kill any existing server.psi process, so that won't work if multiple servers are created. I will let you handle this part as I'm not using the self-hosted mode.

Woah! Nice work @spudwebb

I'll give it the eye over the next few days as well as fixing up host mode with the changes.
I am considering about dropping the reference application, as it's causing too many delays in getting v4 released.

Question: How much have you tested the lib, I wouldn't imagine every method has been tested (or has it)?
I would like to think there isn't anything of concern at this point.

Before a release, I will review any critical schema updates to bring it up to date with the server (its only 2 behind)

Thanks for the contributions you have made on the project, it's much appreciated!

We have a beta version of a new ZWave driver for HomeSeer based on this library that we are currently testing internally. This new driver uses a good chunk of the library but not every methods.
The things that we do not have tested at all are:

• Use of the library in host mode
• Virtual nodes
• Node/Controller/Route statistics
• MethodFactory

If it helps, I have tested Virtual Nodes and are consuming the statistics for display purposes. Not doing anything more than just displaying stats. Beautiful piece of work folks!!!!

Thanks @georgeinva2004

With all testing that seems to have taken place - I will try my upmost to get a release window in (along with this PR)

Thanks both 👍

My solution to host mode is as follows..

1. A copy of the server (server.psi) is made, but named along with the configured port (server.50001.psi)
2. This copy is what will be run.
3. but not before killing (and deleting) any instances of this copy

 internal void Start(string SerialPort, ZWaveOptions Config, int WSPort)
 {
     string ProcessName = string.Format("server.{0}.psi", WSPort);

     Process[] Zombies = Process.GetProcessesByName(ProcessName);
     foreach(Process Zombie in Zombies)
     {
         Zombie.Kill();
         File.Delete(ProcessName);
     }

     if (!File.Exists("server.psi"))
     {
         throw new FileNotFoundException("No Platform Snapshot Image (server.psi) found");
     }

     File.Copy("server.psi",ProcessName, true);
     ...
     ProcessStartInfo.FileName = ProcessName
     Process.Start()
     
}

This should allow mulitple servers if starting up multiple Self Hosted instances (I will check for ports already in use)

Sorry - got pulled away - I'll look to merge this over the weekend along with the host changes
