- * - Build an hashtable whose keys are the names of the groups
- * (fourth field in each line of dictionary) and whose corresponding
- * values are lists of all the dictionnary entries among that
- * group. Note that apparently the Dicom standard doesn't explicitely
- * define a name (as a string) for each group.
- * - A typical usage of this method would be to enable a dynamic
- * configuration of a Dicom file browser: the admin/user can
- * select in the interface which Dicom tags should be displayed.
- * \warning
- * - Dicom *doesn't* define any name for any 'categorie'
- * (the dictionnary fourth field was formerly NIH defined
- * -and no longer he is-
- * and will be removed when Dicom provides us a text file
- * with the 'official' Dictionnary, that would be more friendly
- * than asking us to perform a line by line check of the dictionnary
- * at the beginning of each year to -try to- guess the changes)
- * - Therefore : please NEVER use that fourth field :-(
- * *
- * @return An hashtable: whose keys are the names of the groups and whose
- * corresponding values are lists of all the dictionnary entries
