Fixes #248 Adds tieWith

[ivan-kleshnin]

An attempt to implement #248

The problem I have is a coverage drop from 100% to 99.8%.

  278 passing (184ms)


=============================== Coverage summary ===============================
Statements   : 99.81% ( 523/524 )
Branches     : 99.4% ( 165/166 )
Functions    : 100% ( 138/138 )
Lines        : 99.81% ( 523/524 )
================================================================================

I guess that's because of the following !!! (condition branch).

_.tieWith = function(separator) {
  assertString(separator);
  return this.map(function(args) {
    assertArray(args);
    if (args.length) { // !!!
      assertString(args[0]);
      var s = args[0];
      for (var i = 1; i < args.length; i++) {
        assertString(args[i]);
        s += separator + args[i];
      }
      return s;
    } else { // !!!
      return "";
    }
  });
};

I dunno how to create the case where args would be [] :(
Hope for your advice.

Hmm, for the coverage issue, what about this?

Parsimmon.of([]).tie().tryParse("")

Thanks for the PR by the way! 😄

Updated.

Thanks! I'll merge this tonight when I have time to update the changelog and do the release
