require('bloodtype-validator')( 'a', 'strict' ) // returns false
require('bloodtype-validator')( 'a+', 'strict' ) // returns true
 
require('bloodtype-validator')( 'a', 'strict', function( error, is_valid ){
  
  // is_valid === false
});
require('bloodtype-validator')( 'a+', 'strict', function( error, is_valid ){
  
  // is_valid === true
});
