Use GEMOC ANR Documents to improve GEMOC documentation about model animation and debug component

As stated in the note in http://download.eclipse.org/gemoc/docs/nightly/_components_documentation.html#_simulation_model_animation_framework, the document http://gemoc.irisa.fr/ins-pub/m30/gemoc-anr-d4.3.1-v1.0.pdf from GEMOC ANR project contains several sections that would be useful to move to the documentation.

Even if this document is quite old this part of the framework hasn't changed much, so the verification and adaptation should be easy.

Start with the note in the GEMOC components documentation at http://download.eclipse.org/gemoc/docs/nightly/_components_documentation.html#_simulation_model_animation_framework and compare it with the relevant sections of the GEMOC ANR D4.3.1 PDF. Verify which material still applies to model animation and the debug component, then update the documentation with the adapted content.
