json_decode as array instead of object

This is a great utility class! I think it would be nice to have configuration option to do all of the json_decode calls with the $assoc variable as true, to get back an associative array instead of an object. You could have a variable in the constructor that would be set to false by default, but could be passed in as true.

Personally, when I implemented the class, I changed all of the json_decode calls in the class to be like this:
json_decode($response, true), but I think that a config option makes more sense for the majority of users.
