Implementation of a command line interface (CLI)

[thomas694]

As already mentioned (#159, #195, #57, #163) a few times before, it would be helpful if TumblThree could be run without a GUI. This would even make it possible to run TumblThree on other platforms.

For that to be accomplished there are the following major tasks to be done:

• Definition of the necessary commands and options. This task isn't related to developers, everyone who likes to specify it (e.g. commands, options, default values, help texts) is welcome.
• Researching and implementing a CLI library. This command line parser library could be a good choice, but hasn't to be the final decision.
• Research new start behavior. As the application will be started either with GUI or from the command line, there needs to be found a way how to do this. Either one exe for both start types or a separate one for each type. This link looks like a good starting point.

These tasks are a starting point and can lead to sub-tasks and further refinement as things evolve.
