added about.html page 

submitting about.html (sooo happy!!), however I still have the previous environment before Wednesday's meeting. Thanks for the review and suggested improvements. 

I will fetch&merge now all the changes from Wednesday's meeting and try to upgrade the about.html in accordance with current goals. 
Thank you!!!
see my settings, urls...I have text from git (like HEAD, >>>>, origin/master...) between my code lines. No idea why, so I am checking now CC/TrackCat repo on github and deleting whatever was added and do not belong there by my best knowledge...
