/**
* @class vtkVariantCast
*
* Converts a vtkVariant to some other type. Wherever possible, implicit conversions are
* performed, so this method can be used to convert from nearly any type to a string, or
* from a string to nearly any type. Note that some conversions may fail at runtime, such
* as a conversion from the string "abc" to a numeric type.
*
* The optional 'valid' flag can be used by callers to verify whether conversion succeeded.
*
* @par Thanks:
* Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
