Use benchmark with composer

[adriengibrat]

Hi,

Your lib is great! please add it to https://packagist.org, so everyone can use it with composer ;)

Well, I thought this library is good only for some relative tests (because for accurate measurements it's much better to use profilers). But I'll add it to composer's repository soon then, thank you for your idea!

You can now find this package at https://packagist.org/packages/almadomundo/benchmark (it's on auto-update, and, therefore, all changes would be applied immediately)
