Please add createReader function about excelbundle HOT 2 CLOSED

Hello pivasyk,
thanks for reporting,
PHPExcel provide the load function
eg.

$objPHPExcel = PHPExcel_IOFactory::load("MyExcel.xlsx");
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {... 

If you need to use with this library

1. Is very simple, you should add a function into Service/ExcelContainer.php called maybe load, for input takes the file to load and return the PHPExcel object.
   Into the function you should do something similar to CreateWriter except for the
   -rename $factory_method to load
   -rename $this->writer to $phpObject
2. into config/services.yml you need to create a service very similar to xls.service_xls5

I hope this was clear, let me know

PS: a pull request 'd be great!!

Sorry i just release some code, and the tips i gave is deprecated :)
is still easier all the modification that you have to do are on services.yml

Create a new factory similar to xls.factory_xls5

1. find the correct class
2. replace createWriter with load
3. set an arguments: 'filename'

this example is for a static filename, is not so difficult create a service for it.
