Template logic

The template logic for ASP.NET 2.2+ is as follows.

1. Scaffolding checks for the Bootstrap version number under the path wwwroot\lib\bootstrap\dist\js\bootstrap.js.
2. The process attempts to discern the existing bootstrap version and provide appropriate content. If no bootstrap version is detected, the generated default content is for bootstrap 4.
3. The bootstrap 4 content goes into the directory: Templates\ViewGenerator\
4. The bootstrap 3 content goes into the directory: Templates\ViewGenerator_Versioned\Bootstrap3\
