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!!!
there are some spaces in the last line, that's why git/github still complains that there is no newline at the end of the file
never mind for now, I'll fix it, but for future reference, a newline (empty line) is needed at the end of the file... no spaces, no tabs, nothing!
