* \brief Abstract superclass defining the Transform IO interface.
*
* TransformIOBase is a pure virtual base class for dervied classes that
* read/write transform data. It's used by the TransformFileReader and
* TransformFileWriter classes. End users don't directly manipulate classes
* derived from TransformIOBase; the TransformIOFactory is used by
* the Reader/Writer to pick a concrete derived class to do the actual
* reading/writing of transforms.
