Corrected interchanged characters
Changed color of chosen objects to a more lighter one. This makes it easier to identify other rendered informations.
Few changes in CylindricalGear and new normal function in Spline class.
Added SimpleGear class, ToothProfile interface and SplineToothProfile class, which inherits SimpleGear and implements ToothProfile
Replaced QVector in basic object Spline classes by std::vector.

REFACTORING Combined ObjectScheduleTreeView and ObjectScheduleWidget to one class ObjectScheduleViewWidget

REFACTORING Renamed ConnectionModel to SelectionModel
