Feature: Getting options from environment variable

In order to avoid having to type --rspec over and over
A user will need to set up a JUWELIER_OPTS environment variable

Scenario: Environment variable set
  Given a working directory
  And I set JUWELIER_OPTS env variable to "--rspec"
  When I generate a project named 'the-perfect-gem' that is 'zomg, so good'
  Then 'spec/the-perfect-gem_spec.rb' should describe 'ThePerfectGem'
