// .NAME vtkVariantExtract
// .SECTION Description
// Performs an explicit conversion from a vtkVariant to the type that it contains. Implicit
// conversions are *not* performed, so casting a vtkVariant containing one type (e.g. double)
// to a different type (e.g. string) will not convert between types.
//
// Callers should use the 'valid' flag to verify whether the extraction succeeded.
// .SECTION Thanks
// Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
