63751de912 Changes in EP/EPDTC to fix numerical issues and increase the flexibility of the inference. 
Changes to avoid numerical issues and improve the performance:
    - Keep value of the EP parameters between calls
    - Enforce positivity of tau_tilde
    - Stable computation of the EP moments for the Bernoulli likelihood
    - Compute marginal in the GP model without directly inverting tau_tilde

    Changes to improve the flexibility:
    - Add parameter for maximum number of iterations
    - Distinguish between alternated/nested mode
    - Distinguish between sequential/parallel updates in EP
