GuzzleClientFactory not found

[Adam]

Probably not an issue, more likely how I am using it!

I am getting;

Fatal error: Uncaught Error: Class 'Thepixeldeveloper\Mondo\GuzzleClientFactory' not found in...

Installation was by composer and I have been sure to update dependencies. Should this class be included in the dependancies or do I need to install something else? I am requiring autoload.php

Thanks in advance.
