const StatesService = require('atm-states');
 
var s = new StatesService();
s.getEntry('000ABCDEFGHIJKLMNOPQRSTUVWXY', 1)
> 'A'
s.getEntry('000A001002003004005006007008', 2)
> '001'
s.parseState('000A870500128002002002001127')
>{ description: 'Card read state',
  number: '000',
  type: 'A',
  screen_number: '870',
  good_read_next_state: '500',
  error_screen_number: '128',
  read_condition_1: '002',
  read_condition_2: '002',
  read_condition_3: '002',
  card_return_flag: '001',
  no_fit_match_next_state: '127',
  states_to: [ '500', '127' ] }
