Docker container installation of TetraX2.0

Dear Users,

In case you are installing TetraX2.0 in a docker container environment, please keep in mind that additional libraries are required for the gmsh package we use for mesh generation.

On Ubuntu the following command needs to be included into the docker code:

apt-get -y install libglu1
libxcursor-dev
libxft2
libxinerama1
libfltk1.3-dev \
libfreetype6-dev
libgl1-mesa-dev

Good luck and enjoy TetraX2.0!

Attila
