bundle
ruby questionnaire.rb

Current implementation separate on two sides: UserQuestionnaireService and StoreService. UserQuestionnaireService is responsible for the working with user questions:

1. processing answers
2. counting ratings

StoreService is responsible for the working with pstore:

1. saving in file
2. getting data from file
3. getting keys/values etc. I tried to make this service without relying on this task. So that in the future it could be reused for various purposes.
