ajout d un fichier pour tester la branche
premier commit de la branche test
fichier ajoute : filetest (vide)
commit de l'ajout du fichier essayonsStash via stash, cree dans la branche autretest et enregistré dans la branche test
Ajout des fichiers .h .ih et .cpp correspondants à la classe Board3D

ceux-ci reprènnent fidèlement ceux de la classe Board3DTo2D en épurant les méthodes et attributs liés à la caméra et à la transposition 2D.

Remplacement de la méthode saveCairo par saveObj, nouvelle méthode actuellement vide.
Modification de la methode saveOBJ
Modification de saveOBJ et exemple simple
debut d optimisation de code
one list => one object OBJ
and some other edits in order to clean the code
as adding ASSERT for checking the modes
and temporary streams to inore void lists
Merge branch 'master' into board3D
 # change method of drawing

now a voxel coordinate is the center of it and not his upper left vertex
and the lines are always draw in the same way regardless of the mode
Merge branch 'master' of https://github.com/DGtal-team/DGtal into board3D
 # The name of the sub list is more correct

may still have conflict if two differents sources add the same type of list
 # starting the implementation of the .MTL export

in order to save the informations about the color and the transparency
 # add a kalimsky test
very similiar to the test of viewer3D
 renamming
Merge branch 'master' into board3D

Conflicts:
	src/DGtal/io/Display3DFactory.ih
	src/DGtal/io/ModuleSRC.txt
and change Board3D to make it compatible with the modifications on the
branch factoryEmbedding
 #change the tests with Board3D

they're now adapted to a template class
 #firsts steps mtl export

the board now starting to export the materials with the geometry
 #export materials and clipping planes

now the clipping planes are taken into account to display or not the
figures, except themselves- the quadD3D list -
 #adding doc to explain what board3D can do

and modifiing a little the code in consequence
 # remove some misspelling
 #one material per surfelPrism
