Procedures for adding migrations to our Rails application.

1. Add your migration file

There is a rails tool to help you make the file. For example, if I wanted to add an age column to the users table, I would run:

>  rails g migration add_age_to_users age:integer
      invoke  active_record

How to solve this "special" goals question.

Since we are saving the questions through the cycle model via the
`accepts_nested_attributes`, feature in Rails, we don't need to make
more than one ajax call when saving the questions.  When we save all
the questions data, we will also use this "special" goals question (GQ)
to add the following fields to the save data.

  * cycle.goals_question_type
  * cycle.goals_question_multchoice_desc

/**
 * FORM FIELD CONFIGURATION
 *
 * In the configure-cycle.js view, we will determine what type of
 * cycle we are dealing with, and choose the correct configuration
 * object. The keys of these configuration objects represent the file
 * name where the subview lives. The value represents the options
 * object that will be passed to the view's initialize() method.
