Release 1.2

Blog post for this release.
TL;DR: python ! 🎉

New Features / Critical Changes

• New Feature

  • DGtal now has a python binding pip install dgtal! For all
    details on the list of classes available in python, you can have a
    look to: Pablo Hernandez-Cerdan #1528

• Geometry Package

  • New normal vector estimation using plane-probing approaches.
    (Jocelyn Meyron, Tristan Roussillon,
    #1547)
  • New normal vector estimation using slices of digital surfaces
    and maximal segment computation
    (Jocelyn Meyron, Tristan Roussillon,
    #1547)
  • Add an implementation of the Quick Hull convex hull algorithm. It
    works in arbitrary dimension. It provides several kernels to deal
    with lattice or rational points, and also to compute the Delaunay
    cell complex.
    (Jacques-Olivier Lachaud,#1539)
