/** 
  * Test et comparaison des methodes geometriques de differentes bibliotheques.
  * Sont prevues : Oracle, Jts, Geos.
  * On peut facilement completer le test par de nouvelles bibliotheques 
  * en creant une nouvelle classe fille de GeomAlgorithms 
  * et en l'appelant dans cette application.
  * Le programme genere des images et des fichiers SVG compresses. 
  * Un fichier de comparaison des temps de calcul entre les differentes bibliotheques est aussi genere.
  * On charge un nombre progressif d'objets, en utilisant le rectangle englobant (enveloppe) des couches testees
  * et en faisant varier par un facteur la taille de cette enveloppe (variables a regler au debut du code). 
  * A l'aide d'une boucle, on charge progressivement de plus en plus d'objets.
