A first pass at a CSV API which provides header-based access plus error handling

better_csv_spec.rb

describe BetterCsv do
  it 'has a nice API' do
    parser = BetterCsv.parse('info.csv', headers: :first_row)
    parser.each_row do |parse_result|
      next if parse_result.error?
      puts "Found the name and phone #: #{parse_result.name}, #{parse_result.telephone}"
    end
  end
end

This could have a second way to check for errors, throwing an exception instead of returning a boolean. Similar to ActiveRecord#save vs. ActiveRecord#save!

E.g., instead of using parse_result.error? the user of the library could choose to call parse_result.validate! which would throw the CSV parsing error, else take no action.
