Remove Jobseeker/Job Report test for now, in favor of starting with simpler reports.
Add spec for the pending JobseekerList class, testing whether it lists Jobseekers in alphabetical order of their name.

Add Name#to_string in order to fulfill Rule 6: Don't abbreviate.
Add JobseekerList class, which supplies an ordered array of Jobseekers through #jobseekers_as_array.

Update Jobseeker spec to use #as_array instead of #jobseekers_as_array, in keeping with Rule 6: Don't abbreviate.
