Work in Progress

...At this stage the code is a constant work in progress!

How it should work: evey method in the tools is as direct as possible and works for nibabel images or for numpy arrays or for some other basic data type.

Tools should be tested.

To apply the methods in the tools directly to nifti images, given paths, they can be accessed via a facade. Facades are divided by aims, and each is called agent: an agent provides a way to access a set of tools, working directly on their paths.

Agents do not need to be tested.

Being a work in progress, there can be methods in tools acting directly on paths (ending in _path), and not yet integrated in the agents, and there can be methods not yet tested.
