Initial version of the variational segmentation, done with Nicolas Toussaint
Update class names after rebase
Update CMakeLists.txt
double to float, reduce dimension of input image to gain in speed and use less memory
wip
get rid of the v3dView dependency
-ITK4 migration.
- I used the vtkLandmarkManagement Project to add visible landmark. This
  solution is temporary but working to a certain point.
working version with widget2d based on vtkhandlewidget
add a if to test whether an observer has already been added or not
changes to use the backend
Widget 2d visibile on all orientation with correct position, sphere widget not visible in 2d and not movable. we cant add landmark in 3d now, however need to test to be sure, bug with the delete of landmarkwidget because of event
adds a button (and code) to generate the binary (not working yet), comments the line for delete
working version for generating binary image, however the binary image is of low quality (WIP)
working version for generating a binary image
bringing the maskApplication plugin for the Party git status
moving forward with apply mask button
This commit brings severals improvements to the varSeg plugin :
- The possibility to apply the current segmentation to the image
- a start button that activates the segmentation mode
- a cross cursor when the segmentation is activated
- a Abandon button which brings back the original image
- after clicking on the start button, the currentView variable wont be
  changed, this choice should prevent bugs if several images are opened
There are still several bugs :
- focus loss (works only in windowing mode)
- windowing setted to 0/1 when the data is setted (see applyMask or
  Abandon)
- removing landmarks from 2d view does not work
- binary image generated does not look that good (borders, ...)
Resolves the window level bug
it is now possible to perform multiple segmentation one after the other
defines a new shortcut for the outside constraint
