WIP
Create, without implementation, the 'no-tag' feature
Additional options

 » Change 'no-tags' option to 'omit-tags'
 » Add new option 'omit-service'
Add tags to services and create new ones
Service methods for querying different kinds of names
Trying design ideas

 » Add 'byebug' gem
 » Move scraping code to its own class
 » Move printable module code to format; maybe I can reuse some
 » Design a DSL for defining services
 » Convert some services to that DSL
