option to covert to british system like lakhs, crores etc

[nagasudhirpulla]

Hi, I like this library.

But I am from India and we use lakhs and crores instead of millions and billions.

Can we have this option in this library.

Thanks

function inWords(numIn) {
  var inWordsSub = function(num) {
    var a = ['', 'One ', 'Two ', 'Three ', 'Four ', 'Five ', 'Six ', 'Seven ', 'Eight ', 'Nine ', 'Ten ', 'Eleven ', 'Twelve ', 'Thirteen ', 'Fourteen ', 'Fifteen ', 'Sixteen ', 'Seventeen ', 'Eighteen ', 'Nineteen '];
    var b = ['', '', 'Twenty', 'Thirty', 'Forty', 'Fifty', 'Sixty', 'Seventy', 'Eighty', 'Ninety'];
    var n = ('0000000' + num).substr(-7).match(/^(\d{2})(\d{2})(\d{1})(\d{2})$/);
    if (!n) return;
    var str = '';
    str += (n[1] != 0) ? (a[Number(n[1])] || b[n[1][0]] + ' ' + a[n[1][1]]) + 'Lakh ' : '';
    str += (n[2] != 0) ? (a[Number(n[2])] || b[n[2][0]] + ' ' + a[n[2][1]]) + 'Thousand ' : '';
    str += (n[3] != 0) ? (a[Number(n[3])] || b[n[3][0]] + ' ' + a[n[3][1]]) + 'Hundred ' : '';
    str += (n[4] != 0) ? ((str != '') ? 'and ' : '') + (a[Number(n[4])] || b[n[4][0]] + ' ' + a[n[4][1]]) : '';
    return str;
  }
  var nTemp = numIn.toString().split(".");
  var num = nTemp[0].split(",").join("");
  if (num.length > 14) return 'overflow';
  num = ('00000000000000' + num).substr(-14);
  var words = inWordsSub(num.substr(-7))
  var croreWords = inWordsSub(num.substr(0, 7))
  if (croreWords != "") {
    words = croreWords + " Crore " + words;
  }
  return words;
}

This is my implementation, just for reference, this can convert upto 14 digits into words
