Provide interface for loading classes within ByCounter.
Provide convenient access to load classes within ByCounter in order to move input and output parameter handling to ByCounter's realm. The interface must also be present in ByCounterWrapper.
Example: The ConversionManager of the validation needs to be loaded within ByCounter to support instrumented data types. This requires access to the class loader used by ByCounter. The change must be realized in OutManager line 83f.
ByCounters ClassLoader can now be queried using getClassLoader() on the BytecodeCounter class (and ByCounterWrapper). The validation now uses this new feature.
