Repo cleanup #58
Description
Refactor each sample to make it easier to browse.
Add README.txt to each sample solution.
Add primary “Index” readme file as welcome page.
There are some bad class names in the code. MyApp, SampleCppApp , suggest changing to more helpful names.
Document use of the Win32 Toolkit, what is it, where is it? Do I really need it for C++? (yes you do)
