+ * (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 :-(
