Fixing issue #1

Hello,

This lib is just a wonderfull idea ! :+1: 

I have fixed the issue #1

Then I've tried to transform the two script test.php and fixedArray.php into phpunit tests and encounter some other bug linked to namespace. I've fixed this.

I think these tests need to be better than testing output from some var_dump but I wanted to keep closer to the original scripts.

I didn't delete original scripts. Perhaps adding travisCI could be a good improvement.

HTH :beers:
