New path to McStas installation

[kinetik161]

When installing McStas in Debian using the recommended way:

cd /etc/apt/sources.list.d
sudo wget https://packages.mccode.org/debian/mccode.list
sudo apt update
sudo apt install mcstas-suite-python-ng

the paths in the configurator of McStasScript need to be set as:

configurator.set_mcrun_path('/usr/bin/')
configurator.set_mcstas_path('/usr/share/mcstas/resources/')

and not ones with an explicit version number as stated in the McStasScript documentation like /usr/share/mcstas/3.x/.
Version of McStas is 3.5.16.

I suppose the default installation path of McStas has been changed?

There have been changes in how McStas is installed, and even how McStasScript is configured. Now McStasScript actually looks for the $MCSTAS environment variable and use that accordingly, making configuration not even necessary in most cases. That too should be updated in the documentation! Thanks for bringing it to my attention.
