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!!!
