Notebooks detailed checks

[mknorps]

To finish #179, we split the detailed check work of notebooks to a separate issue.

We want tutorials and examples to be:

• easy to run
• run without failure and correctly
• describe their subject clearly
• coherent with the web html renderings
  and this issue is to ensure that.

Tutorials:

• Advanced sampling Notebooks: AdvancedSampling.ipynb #226
• Bayesian Notebooks: Bayesian.ipynb #220
• Introduction
• Lazy Notebooks: Lazy.ipynb #227
• MCMC Notebooks: MCMC.ipynb #223
• SMC Notebooks: SMC.ipynb #225
• Sampling Notebooks: sampling.ipynb #206
