Everything works OK after serious changes:

- all components, componentCfg-s and parameter providers use base classes
 - less boilerplate code, simpler access to test/procedure parameters from code
 - CreateTestParams(test), CreateProcedureParams(procedure) methods added
 - TestBenchSim class is made static, it is not inheritted by any device anymore
