Exports types and methods from Udon into a C# DLL
To install put ExtendedUASM and TooDon Exporter into Assets\Udon\Editor.
Once that's done, at the top a drop down called TooDon will appear. Click that and then click "export udon types".
To use the DLL in Visual Studio for auto complete, remove all reference to other DLLs in your Visual Studio Proejct, then add <NoStdLib>true</NoStdLib> to the .csproj file for your project. Put that line inside one of the PropertyGroups that doesn't have a condition.
