Instead of dumping the documentation scattered around projects, let's have the conversation about EMC here.

@arokem and @dPys, can you please have a look and suggest changes/point out things that seem wrong or even blatantly wrong?

A few small comments and suggestions for now.


**Problem**: although most dMRI practitioners employ FSL for the estimation and correction of head-motion and eddy-current distortions, the FSL toolbox has restrictions of commercial use. By using FSL's eddy implementation, *dMRIPrep* inherits those restrictions.
Therefore, a fully-open implementation of *dMRIPrep* would require eliminating FSL as a dependency.
In this case, we will provide our own implementation of an algorithm for head-motion and eddy-current-derived distortions.

I don't know if I like this framing. Arguably, we want to provide a general, open-source solution that is also best in class. The license issues, though real, seem a bit obscure.
