Wrapper for API v2.0 (.NET Core 2.2)

Updated project to work with the portion of the API v2 that's been released so far. Tagged prior to moving from .NET Core to .NET Standard (more compatibility with other projects and nuget).

Wrapper for API v0.1 (.NET Core 2.2)

This was a wrapper around v0.1 of the API. Tagged so I could update it to work with v2.0 of the API, which was just recently released.

Updated solution to target .NET Core 2.2 instead of .NET Framework 4.x, and added yml file for automated Travis CI builds.

Wrapper for API v0.1

This was a wrapper around v0.1 of the API. Tagged so I could update it to work with v2.0 of the API, which was just recently released.
