    Class implementing a simple registry of test framework interfaces.

    The test executor for a framework is responsible for running the tests,
    receiving the results and preparing them for display. It must implement
    the interface of TestExecutorBase.

    Frameworks must first be registered using '.register()'. This registry
    can then create the assoicated test executor when '.createExecutor()' is
    called.
