Define CRUD.

CRUD stands for Create Read Update & Delete. It allows us to create resources in a database, read or 'get' the resource to display, update a resource without overwriting the original resource and delete a specific resource from the database.

There are seven verb + path combinations that are necessary in a basic Sinatra app in order to provide full CRUD functionality. List each of the seven combinations, and explain what each is for.

All resources: get '/resources' (ex. get '/tasks') => gives us a list of all the resources through a index.erb file that gets interpreted to html.

One resource: get '/resources/:id (ex. get '/tasks/1) => gives us the specific resource through a show.erb file that gets interpreted to html.
