+    dudkFormatPicker shows each column heading mapped to a field whose type has
+    format options from the current spreadsheet, alongside a drop-down containing
+    available formats.  This allows the user to choose a format for
+    each column that needs one, to select how the value mapping should be applied.
+
+    The resulting data to be submitted to the 'importerMapDataPath'
+    will be a map of column indices to format names.
+
+    It accepts a data object which is taken from the prototype kit's
+    session data which is made available on every page, and contains the
+    data submitted from forms to the backend, and also the current
+    data import session.
