removed enrollments controller and changed the enrollment process to now included enroll in a group and then add coach instead of in one process - this also required removing views. Also I removed some gems except for phonelib from the gemspec file.
updated text in group panel for users to improve clarification
updated validations on participants for enrolling [Finishes: #81109176]
fixed rake error
updated readme with new rake tasks for seeding fixtures along with removed emails and changed them to study_id
added changelog
