Adds an additional parameter roundtripValue to function data.

Browse Source 
Enables a stored value, which can be passed by the function 'result' to the next call of the function 'data'.

This is a solution for issue #72

Example:

    data: function (term, page, roundtripValue) {
      var options = {
        q: term,
        limit: 5,
      };
      if (typeof(roundtripValue) !== 'undefined' && roundtripValue != null) {
        options['continuation_handle'] = roundtripValue;
      }
      return options;
    },
    results: function (data, page) {
      var roundtripValue = data.continuation_handle;
      var more = typeof(roundtripValue) !== 'undefined';
      return {results: data.results, more: more, roundtripValue: roundtripValue};
    },
