Add "about" page

[dgarijo]

Stating who the team involved is and their role

[m-markovic]

Should we not just link to the TEC Toolkit page?

[dgarijo]

that would be an other option too

Added section in the README (as suggested in the template).

Tracked for the remaining repositories somewhere else.

Sorry, this is not intended to just the readme. The HTML should have some sort of description of the team behind it, and the link to the TEC Toolkit
