Description:
    Generates a skeleton for a new feature. Both a simple .feature file and
    a steps.rb file is generated. This generator should be used with moderation.
    See http://github.com/aslakhellesoy/cucumber/wikis/feature-coupled-steps-antipattern
    for details about the dangers involved.

    This generator can take an optional list of attribute pairs similar to Rails'
    built-in resource generator.

Examples:
    `./script/generate feature post` # no attributes
    `./script/generate feature post title:string body:text published:boolean`
