Performs the IntroSort algorithm
(this is a beta version)
========================================

# Example using jQuery

  var compare_function = function(val1, val2){
    return val1 < val2;
  };
  var switching_function = function(val1, index1, val2, index2 ){
    console.info( val1 + ' is now at position: ' + index1 );
    console.info( val2 + ' is now at position: ' + index2 );
  }
  $.introSort( array, compare_function, switching_function );


# Example using no js framework

  var compare_function = function(val1, val2){
    return val1 < val2;
  };
  var switching_function = function(val1, index1, val2, index2 ){
    console.info( val1 + ' is now at position: ' + index1 );
    console.info( val2 + ' is now at position: ' + index2 );
  }
  
  introSort( array, compare_function, switching_function );
