- Upgraded files using new version of WinFlexBison - Removed global variables within StepFile_Read.cxx - Upgraded error message during bison analyzing ( added a expected expression information ) - Used 'Interface_ParamType' as argument type for the StepFile_ReadData::Argument for a compatibility with the StepData/StepData_StepReaderData - Added handling parse errors and transferring it to the StepData_StepReaderData - Now parsing and referencing errors save in the check and non output by default - Step_file's and Step_Data's output info prints according by trace level of printer - Removed useless location.hxx - Removed TraceLevel for the StepFile_Reader ( now it useless, it is 0 by default and newer and nowhere change ) - Translate error message into English within StepData_StepReaderData - Replace "Error" word in the output messages
