simplified command line interface

@Marcdh3 I think something like this provides more intuitive and user friendly cli interface for ornet tool. cheers

Thank you for the PR, because we were planning on transitioning the code to a simpler cli. However, we were considering using a main.py for clarity. Are there any advantages to using the entry_points option in setuptools, rather than a main.py?

@Marcdh3 I'm not exactly sure what you mean by using main.py ? As in the user will type main.py on the command line? or you going to rename one of the modules into e.g Pipeline.py -> main.py ? The latter wouldn't change anything, the former is sort of upto you, but you want to make sure it is initiative to the user. If the tool called my-tool I sort of expect it to be the same name on the command line, but it doesn't have to be I guess.

entry_points is the way to specify "main" function, as in the function that going to run first.

There are various ways of doing what I've done. Another way I've seem people do this is to make scripts or bin directory and place ornet.py into that directory. That way user just finds that and runs it.

Feel free to knock-back the PR this was just an example, has no effect on the review

Cheers

Oops, I wrote "__main__.py", but the markdown removed the '_'. Thanks a lot for the tip! Taught me a new way to do that. We stuck with the original plan, since it sounds like they achieve the same functionality, and using this file may make it easier for someone exploring the directory to have a common starting point.
