Boston University students will contribute work they do for class to Boston.com, a website owned by The Boston Globe, which is part of The New York Times Co., the company said Tuesday. The photos and stories will be part of the site's "Your Town" section, which focuses on neighborhood and municipal news. The program will launch later this year.  Globe regional editor David Dahl said the collaboration will give readers more local coverage while enriching the experience of BU students. "Your Town" launched in 2009 and focuses on 12 Boston neighborhoods and more than 30 other Eastern Massachusetts cities.
