json2args Octave package

[AlexDo1]

We need to create an Octave package json2args (like the Python package json2args).
The Octave package should be published on Octave forge. This way we can always install the needed version directly from the server and get rid of get_parameters.m, which is currently used to parse parameters from the .json file, but is hard to maintain as changes have to be copied manually to each tool.

• setup the Octave package json2args on Github
• implement get_parameters.m into the created package
• publish the package on Octave forge
• check if and how it is possible to make the package available in Matlab
