In static_pages_spec.rb, update to use of 'before {visit xyz_path}'
In static_pages_spec.rb, 1. add 'subject { page }' once, to replace expect(page) 10 times, 2. alternate (shorter) syntax for 'it' blocks.
Create 'rspec utility' (essentially a helper, but for Rspec specs) to remove redundant 'Ruby on Rails Tutorial SampleApp3' from spec tests. 1. create utilities.rb 2. create the utility (aka, the method/helper for rspec) in file 3. Replace lines in static_pages_spec.rb to user full_title() utility (no import nessesary. 'Utilities' are automatically added to rspec.)
