Public: Allows fields on a class to be composed/decomposed to
 Pinpoint::Addresses.

 field_name - The object to apply the accessors to
 options    - A Hash of options to apply to the method call

           :validate   - A Boolean describing whether to include
                         ActiveModel::Validations into the class for the
                         address fields.
           :prefix     - If set, then all fields which make up the Address
                         will be prefixed with that string (eg: #venue_city
                         instead of just #city) If you do not want field
                         names to be prefixed simply set it to false.
                         (defaults to the field name).

 Example

   # Implicit Prefix (will look for fields such as 'address_city')
   pinpoint :address

   # Explicit Prefix (will look for fields such as 'venue_city')
   pinpoint :location, :prefix => :venue

   # No Prefix (will look for fields such as 'city')
   pinpoint :location, :prefix => false

   # Include field validations
   pinpoint :address, :validate => true

 Returns nothing
