Foreman does not use any 3rd party wizard tool. You can see wizard when you 
create new taxonomy (location or organization) or a good example could be 
foreman_setup plugin [1]. So we use own helpers for that.

Wicked gem seems handy and have no extra dependencies so it should be easy to 
package. Code looks good, my only concern was hardcoded I18n for translations. 
I'm not sure whether it's problem or not, will look at that tomorrow.
