extend sirange class to allow different ranges depending on the execution mode; change valid range for gross vehicle weight depending on declaration or engineering mode

adapting cycle gearbox when using torque converter (incl. some refactoring), adding testcases for measured speed powersplit and serial TC

adding column tc_active to driving cycle (measured speed), extending cycle gearbox by torque converter, adding testdata for measured speed test AT gearbox

adding shift polygon for torque converter gear, adapt shift strategy to check for torque converter shift polygon, added rules for C->C shift

adapting gearbox file: maxTorque, shift polygon for torque converter

ComputeShiftPolygon: Exception when less than 2 gears are given, GUI UpdatePic checks for Gear-Count > 1

a smaller tolerance causes that the next simulation interval will be smaller than the minimum simulation interval and thus cause other issues (e.g. high inertia torque from engine, etc.)
