* \brief FileStreamer
* \details This class let a user create a massive DICOM DataSet from a template DICOM
* file, by appending chunks of data.
*
* This class support two mode of operation:
* 1. Creating a single DataElement by appending chunk after chunk of data.
*
* 2. Creating a set of DataElement within the same group, using a private
* creator for start. New DataElement are added any time the user defined
* maximum size for data element is reached.
*
* \warning any existing DataElement is removed, pick carefully which
* DataElement to add.
