Generates the JSON Win32 metadata files for https://github.com/marlersoft/win32json
Before running the Generator, you'll need a place to store the JSON files. The generator will look for a directory named "win32json" in any of its parent directories (relative to CWD). You can create this directory by cloning the win32json repository to a subdirectory inside this repository or any parent directory.
git clone https://github.com/marlersoft/win32jsonRunning `Generator/JsonWin32Generator.sln" will generate the JSON files with "Visual Studio 2019", otherwise, see RunningWithoutVisualStudio.md.
