Crud implementation of search view controller.
Next steps:
1) search results should have attributed string
2) search button should show up only when user has default university
3) introduce concept of default university and remove hardcoding for schoolId = 1
4) make all the cells tappable/actionable, should lead to proper navigation tab or modal.
