Description:
    The resource generator creates an empty model, controller, and functional
    suitable for inclusion in a REST-like, resource-oriented application.
    
    The generator takes the name of the model as its first argument. This
    model name is then pluralized to get the controller name. So "resource
    post" will generate a Post model and a PostsController and will be 
    intended for URLs like /posts and /posts/45.
    
    As additional parameters, the generator will take attribute pairs
    described by name and type. These attributes will be used to
    prepopulate the migration to create the table for the model. For 
    example, "resource post title:string created_on:date body:text 
    published:boolean" will give you a Post model with those four attributes.
    
    You don't have to think up all attributes up front, but it's a good
    idea of adding just the baseline of what's needed to start really
    working with the resource.
    
    The generator also adds an appropriate map.resources declaration to 
    your config/routes.rb file, hooking up the rules that'll point URLs to 
    this new resource. 
    
    Unlike the scaffold_resource generator, the resource generator does not
    create views or add any methods to the generated controller.
    
Examples:
    ./script/generate resource post # no attributes
    ./script/generate resource post title:string created_on:date body:text published:boolean
    ./script/generate resource purchase order_id:integer created_at:datetime amount:decimal
