A CLI wizard for generating things

[raghubetina]

A CLI wizard to help students generate things; rails generate wizard should walk them through:

• draft:model (rename to table?)
• migration
• draft:resource (rename to resource?)
• draft:layout (rename to layout?)
• account

It should be conversational, similar to web_git:

• What do you want to do?
  1. Create just a table.
  2. Modify a table.
  3. Create a table and RCAVs to CRUD.
  4. Create a layout file (add option to name the file something other than application.html.erb)
  5. Create a table with password columns and sign-in/sign-out RCAVs.
• Based on the response, present new options. E.g. if "Modify a table" is selected,
  1. What table do you want to modify? (If we can introspect and present options that would be great, otherwise they can type and we can normalize.)
  2. Do you want to add or remove a column (don't allow renaming due to Heroku/Postgres issues?)?
  3. Which column do you want to remove?
  4. etc
