 	- Add .NET Standard 2.0 and .NET 4.6 build targets so that users of more modern frameworks can take advantage of more modern APIs. The .NET Standard 1.3 and .NET 4.5 targets will likely be retired in the event of a 2.0 release.
 	- Allow for setting piping and redirection via a `Shell` option with the new `Command(Func<Command, Command>)` option ([#39](https://github.com/madelson/MedallionShell/issues/39))
