 *''palette'' rules:
 ** the palette description is given by two folders, one for nodes, named '''Nodes''', one for edges, named '''Edges'''.
 ** in these folders, the tools should be sorted alphabetically, but the organization also depends on the frequency of use of each element.
+** the label of elements in the palette must have spaces when they have a composed name: '''Data Type''' instead of '''DataType''', '''Duration Observation''' instead of '''DurationObservation'''
