Develop script to launch solutions and perform tests

[goetzst]

To make interaction with the benchmark framework as seamless as possible we want to provide a simple script to launch submitted solutions and run our tests on them.
The following tasks should be completed for this:

• Decide on scripting-language (bash vs. python)
• Agree on how solutions declare how to run their executable
• make a CLI executable from model comparator to check if models are similar

Script to check correctness added with #19
It is written in bash, solutions have to write a launch.env file to specify how to build and launch the solution.
