Update Readme.md

[EricBoix]

• clean up the original UD-Viz-template Readme.md page that got copied here
• point to the computations page
• Polish that computations page by
  • pointing to this demo
  • removing the mentions about how to display the data (this demo is here for that)
• Within that computations directory trying adding the Dockerfile that reproduces that computation (i.e. the content of the Readme.md instructions

Concerning the deployment

• Add an entry (mutatis mutandis) for this démo equivalent to this file
• Point that new page within this readme.md page
• Add the port used for this point cloud demo in the ReadmeAdmin.md page
• Fix the LABEL entry of the Dockerfile to match the repo name

All done except the Dockerfile, I'll try and do it once I get around the laszip problem : either found a way to download a CLI compiled version or another tool to transform .laz to .las.

@clementcolin If your "laszip problem" concerns its installation, what about trying (inspiration sources : LASzip/.travis.yml and ci/script.sh) something like the following in the Dockerfile

[...]
RUN git clone https://github.com/LASzip/LASzip   && \
         cd LASzip/                                                       && \
         mkdir build                                                      && \
         cd build                                                           && \
         cmake ..                                                          && \
         make                                                               && \
         make install

The above is reported to work on a host with

• 18.04 (bionic) (lsb_release -a)
• g++: Ubuntu 7.5.0-3ubuntu1~18.04 (g++ --version)
• LASzip version: 742a314dbe5c16e60f3cf90d26b5 (git log | head -1)
