Convenient task scheduler for JavaScript using Web Workers.

Usage (check index.html for demo):

```javascript

 // setting worker count to 4

 var scheduler = new Scheduler(4);

 // settings common global var for all workers

 scheduler.setVar('prefix', 'result-');

 // setting specific global variable in each worker

 scheduler.workers.forEach(function (worker, index) {

     scheduler.setVar('index', index, worker);

 });

 // importing external scripts

 scheduler.importScripts('test.js');

 // same task for everybody - just for demo purposes

 function workerTask() {

     var start = Date.now();

     while (Date.now() - start < 5000);

     return prefix + index + (arguments.length ? ' (' + Array.prototype.join.call(arguments) + ')' : '') + suffix;

 }

 console.time('tasks');

 scheduler.executeMany(

     {

         first: workerTask,

         second: workerTask,

         third: workerTask,

         fourth: workerTask

     },

     function (results) {

         console.timeEnd('tasks');

         console.log(results);

     }

 );

 console.time('args');

 scheduler.executeForMany(

     workerTask,

     {

         first: [1, 2, 3],

         second: [4, 5, 6],

         third: [7, 8, 9],

         fourth: [10, 11, 12]

     },

     function (results) {

         console.timeEnd('args');

         console.log(results);

     }

 );

```
