Edited home view for Guest user
Added a method to check if org_user. Going to add more
If a non_orgUser goes to index page, he/she can see the orgs they are a part of. 2) Put code in controller so when a person creates an org, this person becomes a member of that org
If a person creates an org, he/she becomes member of that org, but had to comment out some additional code in membership.rb
