Rename, or remove, repo

[brianlagunas]

We should rename this repo to better represent what this repo is for. "demo-apps" is too generic.

Something like "blog-samples" would be better. Then create a folder for each platform so we can put samples for blogs covering all products. For example:

blog-samples
--- angular
--- wpf
--- etc.

However, we already have repos for samples that will be used for support and customers. For example, there is an already existing angular-samples that are to be used for runnable samples. Depending on the sample you are creating, it may be better to put the sample code in the angular-samples repo instead.

This repo may not be needed.

To clarify, I used the angular samples repo as an example. I see you are adding a React sample. Of course, we would place this specific ample in a react-samples repo instead of the angular repo.
