Decrease Doc size by removing some irrelevant content

the current documentation jar is quite big with about 36MB
It seems to contain files that should not be there (images/images/poster.pdf 6.2MB images/images/Tesis.odp 7.5MB)

May be some content from these files should be reused to contribute to the documentation, or may be we should simply point to an online version of it (HAL for the Thesis ?)

Inspect the documentation jar contents, especially images/images/poster.pdf and images/images/Tesis.odp, to confirm what is included and why. Check whether relevant material should remain in the documentation or be replaced with an online reference such as HAL. Done means the unnecessary files are removed or the intended reuse and linking decision is documented.
