class XdmfArray;

//!  Parent Class for handeling I/O of actual data for an XdmfDataItem
/*!
This is the base class for access of values. By default, the
Values are in XML and handled XdmfValuesXML. Otherwise they're 
handled by XdmfValuesXXX (where XXX is the format).

An XdmfDataItem Node Looks like :

\verbatim
<DataItem
  Rank="2"
  Dimensions="2 4"
  Precision="4"
  DataType="Float">
  1.1 3.3 5.5 7.7 9.9 11 13.1 15
</DataItem>
     OR
<DataItem
  Rank="2"
  Dimensions="2 4"
  Precision="4"
  DataType="Float"
  Format="HDF">
    MyData.h5:/AllValues/ThisArray
</DataItem>
\endverbatim

XdmfValues is used to access the "1.1 3.3 5.5 7.7 9.9 11 13.1 15" part wheather it's in the
XML or in a file described in the XML.
This class is overreidden for various formats supported by Xdmf (i.e. XML, HDF5, etc.)
