By moving all checking functions to an external file, it is possible to stop the loading and execution of TypeCzech code by commenting out loading of the
scripts. Note that this moves the function signatures and checking code away from the actual functions to be tested.
<script s r c = "../../web-resources/TypeCzech.js">
<script s r c = "./604-oloo-external-checks.js">
Thus being left with one instruction that loads and executes the checks when TypeCzech has been imported.
if (typeof check_linkUp_first_last_full === 'function')
