Dear openmsr developers,

I was working on issue tickets #5 and #6.
I've created some modifications for Ubuntu22.04 to make these functionalities available.
My concept was to install all the dependent libraries solely into a predefined userspace folder (currently it is $HOME/openmc).
The default definitions of the corresponding environmental variables:

# set the path to the nuclear database
export OPENMC_CROSS_SECTIONS=$HOME"/openmc/nuclear_data/mcnp_endfb71/cross_sections.xml"
# set custom version of pyMOAB
export PYTHONPATH=$PYTHONPATH:$HOME"/openmc/MOAB/build/pymoab/"
# set custom version of CAD_to_openMC
export PYTHONPATH=$PYTHONPATH:$HOME"/openmc/CAD_to_openMC/src/"
# set custom version of OpenMC
export PYTHONPATH=$PYTHONPATH:$HOME"/openmc/openmc/"
export PATH=$PATH:$HOME"/openmc/openmc/build/bin/"

In this way, one can modify all the underlying code without reinstalling that and different versions of OpenMC can be stored beside each other (e.g. $HOME"/openmc/openmc_varA/" and $HOME"/openmc/openmc_varB/" )

The test workflow has been extended with the 3d model conversion and the sample simulation.
(A single hack, i.e. sudo pip install -U numpy was needed due to some numpy API error)

Cheers,
Daniel
