Unify documentation and establish location for demos and demo-data

Currently we have the following documentation sources:

• svn [tvb_root]/docs (here mainly manual/*.rst files can be found)
  This folder gets synchronized with GitHub, and from it we generate the PDFs to be distributed with TVB_Distributions
• we also have [tvb_root]/scientific_library/tvb/simulator/doc folder.... which I think it is not very well positioned, because it is not obvious how to reach it. Wouldn't be better to move everything from here in the previously mentioned "docs" folder, thus easily published on GitHub in raw form?
• 2 new projects have appear on Github... which I do not understand in meaning

Demos:

• currently under [tvb_root]/scientific_library/tvb/simulator/demos ... a bit hidden from the number of questions we got from end-users. Couldn't we create a top layer folder (near "tvb" and "tvb_library_test" to hold these?

Demo-data

• we have a top level folder on SVN named demo_data. We could make it tvb_demo and publish it on GitHub
• there are also (sometime duplicate files) under [tvb_root]/scientific_library/tvb/simulator/files

We should unify these, have a common strategy before we can be published on Neurodebian.

This is the schema I propose for GITHUB:

tvb_root (or TVB) - main repository on GitHub

• license and readme might be the only files left at this level

tvb_root.tvb (python module)
tvb_root.tvb.library
tvb_root.tvb.framework
tvb_root.tvb.tests (full tests; perhaps split in 2 other modules: library and framework)

tvb_root.documentation
tvb_roo.documentation.api
tvb_root.documentation.tutorial
tvb_root.documentation.manuals
tvb_root.documentation.documentation_builder
tvb_root.documentation.third_party_licenses

tvb_root.demo_data (possible as a Python module)

tvb_root.build
tvb_root.build.bin (python module used for generating tvb_distribution)
tvb_root.build.build_resources
tvb_root.build.setup***** (used by pyinstaller)

tvb_root.externals (maybe we can find a better location for it....)
