Modification for loading a few STEP files in the model. Protected by Mutex 1. Loading STEP file in the model with using yacc and lex. 2. Message management 3. Registration in static structure Interface_GeneralLib, Interface_ReaderLib, Interface_Writer_Lib for each StepData_Procotol. Modifications: STEPControl_Controller, STEPCAFControl_Controller were created as not static objects when STEPControl_Reader or STEP_Control_Writes were initialized. Parameters used for translation from Interface::Static were made not static. Map to keep parameters was added in the Interface::InterfaceModel. For STEP translation parameters were initialized during initializing STEPData_STEPModel. model. Static variables were removed. Redundant classes were removed from STEP translator.
