• Resolves Add in automated testing for 32/64 bit nuget package #4214

This adds a simple csharp project that uses a local nuget package to compile and test using a windows .bat test_nuget.bat script. Here is an example of executing the .bat script.

set NUGET_PATH=D:/OSN/build&&^
set NUGET_NAME=OpenStudio&&^
set NUGET_VERSION=3.2.1-alpha&&^
set NUGET_SOURCE_DIR=D:/jenkins/nuget_packages&&^
test_nuget.bat

This tests both x86 and x64 nuget packages by compiling for each platform and then running each compiled .exe.

Ideally, this would be all rolled up into a CMake project. CMake does support nuget packages by using VS_PACKAGE_REFERENCES but this assumes that packages are available via nuget.org which get installed by msbuild during the configure steps. I couldn't find a way to install local .nupkg packages, like the test_nuget.bat script does.

The actual test runs will only be enabled for OpenStudio nightly builds. Incremental builds have this option to turned off to help speed up the builds which are already too slow. Here is a nightly build run that runs the test_nuget.bat script.

This will get enabled when this PR is merged.
