DotA 2 Newbie Team Guide

Provides new DotA 2 players (like myself) help with choosing a hero in pub games. It displays the roles and strengths of the other heroes in the team and offers suggestions about what hero might be a good fit with the team:
- Short summary of each hero's roles and strengths
- Suggests heroes based on what other heroes have already been picked
- Sums up what strengths are already available in the team
- Filter heroes based on roles

Suggestions are loosely based on the win-rate evaluation of reddit user KjellJagland that can be found here: http://siyobik.info.gf/misc/dota2/

NOTE:
Please keep in mind that I'm a noob and only use the statistics available to me. If anyone is interested in improving the app please feel free to share your thoughts at https://groups.google.com/forum/#!forum/dota-2-newbie-team-guide
