* @class vtkXMLPUniformGridAMRWriter
* @brief parallel writer for
* vtkUniformGridAMR and subclasses.
*
* vtkXMLPCompositeDataWriter writes (in parallel or serially) vtkUniformGridAMR
* and subclasses. When running in parallel all processes are expected to have
* the same meta-data (i.e. amr-boxes, structure, etc.) however they may now
* have the missing data-blocks. This class extends
* vtkXMLUniformGridAMRWriter to communicate information about data blocks
* to the root node so that the root node can write the XML file describing the
* structure correctly.
