Refactor Entire Project into .NET Standard (#284)

* Completely refactored the entire solution to just be one .NET Standard 2 project with a unit test.

* Updated dependencies to fix the issue pointed out by @danibjor, and re-added support for AppVeyor through the use of OpenCover.

* Attempted to make AppVeyor support work properly.

* Added AppVeyor code coverage analysis support.

* Added AppVeyor Console unit testing support.

* Corrected syntax formatting across all files in the Parse project, added NuGet package metadata to the Parse project because NuSpec file metadata declaration not supported for .NET Standard projects, added XML code documentation, and modified the AppVeyor configuration to upload the build-created NuGet package to the build console as an artifact.
