 The attached patch tries to extract as much information about a dataset
 from the dataset name as possible. Since accessing attributes is slow but
 the dataset name comes for free this speeds up opening HDF5 files in VisIt
 drastically (I had a factor of 6 when I measured it quite a while ago).

 This is certainly not the nicest way of parsing the string, one could
 think of sequentially looking for "name=value" constructs in the string
 and acting based on the name rather than just matching against all
 possible options.
