Add executive board page

I had a second so I decided to implement the executive board information.  I think this is all that is needed. Personally, we don't need any of this: http://umec.engin.umich.edu/home/who-we-are/exec-board

I was able to embed an iframe with our office hours g-calendar without any problems. So @clharman, you should be good to go for your events calendar.
