Add solrization of the employee datastream.
Add an employees route.
Adds a rightsMetadata stream to employees and makes sure it is automatically set to public.
Add the actual employees route to the front page.
Employee mass_permission autoassignment now works.
Move assignment of public read permission to employee creation job.
Adds the employees route, removes unneeded filter.
Update templates to handle Employee objects in a rough sense.
Add search capability, exact matches on an employee's NUID will now return that employee on general queries.
Update employee_name to be stored as a tesim (stored searchable text) rather than ssim (stored searchable symbol) field.  This allows inexact matches, such as searching only for an employee's last name, to return the employee as a hit.  I assume this is preferable to having to do exact matching on an employee's full name.
