This will be called the first time a toolbox of this type is created. This is meant for installing libraries if they are
needed. For example, if you need boto3 for an Amazon Handler, you would call
FloatingTools.installPackage('boto3', 'boto') here. This is also meant for any other set up such as getting login data.

.. note::
    This is only called once during the first call to create a toolbox if this type.
