Main Application layout scaffold

[mmaelicke]

This pull request add the basic split of the original application. This version will keep as much code as possible from the original, to separate issues and errors into the ones that were already present in RUNISapp.py and the ones caused by the splitting.

With this PR merged, we can start to implement the DataManager and plotting components. It is also the foundation to build the docker branch and finally deploy the first versions.
