Show template for groups

Created show template for group. but not working well without other
related functions. This is very basic show page with links not working.
tried to work on groups controller, user controller, post controller to get groups/ show template working. But it didnt work as too many things interrelated and will have to write code for all of them. Show page is basic but working. created groups/new and form_for_new_group.
Also edited user.rb to associate with the model group.
