<tt>get_export_data</tt> finds records for export using a combination of the default
 export options and the argument options, and returns an array of arrays representing
 the rows and columns of the export data. The first item ("row") in the array will be
 an array of strings to be used as column headers.
 Valid options include :only, :except, :scopes and the standard find options.
 See <tt>to_export</tt> for more details on the options.

 Example:

   User.get_export_data(:only => [:first_name, :last_name, :username])
   # => [['first_name', 'last_name', 'username'], ['John', 'Doe', 'johndoe'], ['Joe', 'Smith', 'jsmith']] }
