Capsul 3.0 depends on sulci-nonfree indirectly, so is broken in the opensource distro

[ylep]

The Axon bindings for Capsul 3.0 depend on morpho-deepsulci for the declaration of Morphologist schemas, which in turns depends on sigraph (sulci-nonfree). Therefore, Axon bindings of Capsul are broken in the opensource distro, even for binding processes that have nothing to do with Morphologist (e.g. neurospin/highres-cortex#15).

H have pushed a workaround (using a try...) but you're right on the problem. The brainvisa schema location is not clear yet, it may move away from Capsul in the future, but at the moment it is used for FakeMorphologist tests in Capsul so I have set this file here.

I have opened a separate ticket #328 for the remaining problem.

That particular issue is fixed for me, thanks! (but I confirm that I am still affected by #328)
