5// This class is part of the Open Inventor Medical utility library.
6//
7// The medical utility classes are provided as a prebuilt library named
8// "fei_inventor_medical", that can be used directly in an Open Inventor
9// application. The classes in the prebuilt library are documented and
10// supported by Thermo Fisher Scientific. These classes are also provided as source code.
