Description:

Stubs out a new resource including an empty model and controller suitable
for a restful, resource-oriented application. Pass the singular model name,
either CamelCased or under_scored, as the first argument, and an optional
list of attribute pairs.

Attribute pairs are field:type arguments specifying the
model's attributes. Timestamps are added by default, so you don't have to
specify them by hand as 'created_at:datetime updated_at:datetime'.

You don't have to think up every attribute up front, but it helps to
sketch out a few so you can start working with the model immediately.

This generator invokes your configured ORM and test framework, besides
creating helpers and add routes to config/routes.rb.

Unlike the scaffold generator, the resource generator does not create
views or add any methods to the generated controller.

Examples:

`quails generate resource post` # no attributes
`quails generate resource post title:string body:text published:boolean`
`quails generate resource purchase order_id:integer amount:decimal`
