New project/directory structure

[gunnar-mb]

Now that the development has reached a certain maturity, it is a good time to reconsider the project structure based on how it has evolved:

Goals:

• Clear separation of each language support, inputs, outputs, transformations and text/jinja templates.
• While things are evolving, get clearer understanding of how each support is implemented (see blog article "5+1 levels of translation methods")
• Fix current module imports in the process (some scripts have to modify paths, etc. and are not cleanly importing the other modules)
• First steps (more later) to strive towards "standard" python-project setup (which is an ever moving target...)

Proposal is edited on this gist for now

PR is here #134

PR has been merged. One useful remaining action would be to copy the gist (update it to make sure it matches the final merged structure) and include in the README some of the explanations about each directory's purpose.
