Bug: Error in example_surface_profiling due to pyglet

When trying to launch example or building the documentation associated to examples using sphinx the following bug occurs:

WARNING: /home/alex/code/slam/examples/example_surface_profiling.py failed to execute correctly: Traceback (most recent call last):

    screen = display.get_default_screen()
  File "/home/alex/softs/miniconda3/envs/slam/lib/python3.6/site-packages/pyglet/canvas/base.py", line 106, in get_default_screen
    return self.get_screens()[0]

    raise NotImplementedError('abstract')
NotImplementedError: abstract

This seems due to pyglet (call for an abstract method i.e. not properly implemented in the code) and apparently occurs from some versions of pyglet see (https://github.com/openai/gym/issues/775) .

A solution would be to remove pyglet and use exclusively visbrain for visualisation in examples

brain-slam / slam
