Export multiple sheets

[rap2hpoutre]

It could be something like:

use Rap2hpoutre\FastExcel\FastExcel;
use Rap2hpoutre\FastExcel\SheetCollection;
use App\User;
use App\Project;

$users = User::all();
$projects = Project::all();

$sheets= new SheetCollection($users, $projects)

// Export all users in sheet 1 and all projects on sheet 2
(new FastExcel($sheets))->export('file.xlsx');

So in other words we could:

• Create a new class SheetCollection (which extends Collection)
• Accept SheetCollection in FastExcel contructor.
• If the paramter is a SheetCollection, then it means each item must be in a sheet.

It seems a simple API.
