'How to' videos: install SDK, import Hello World and OOB projects

I know it is not always easy to reproduce steps in from the user guide, so I shot a few videos on some basic steps which generated some questions in community so far.

In attached zip, you can find 4 videos:

- How to download and prepare RIoT SDK for installation

- How to import RIoT SDK into MCUXpresso

- How to import the Hello World Project from SDK into MCUXpresso

- How to import the Out Of the Box project from Rapid Iot Studio into MCUXpresso

[all zis wiss my formidable axent] in an approximate but hopefully understandable english! :smileygrin:

(I can always rework the videos to add subtitles if needed :smileygrin:)

We will add more videos to further ease your experience with Rapid IoT based on your questions in the community
