/** Utility class for one-stop transformation import.

*
* When writing a transformation using the Write() function, the path or file name suffix determines
* the output file format. Supported formats are: ITK Transformation file (".txt"; ".tfm"), Nrrd deformation
* fields (".nrrd"; ".nhdr"), and legacy TypedStream (all other suffixes).
