-Description: The Poisson-lognormal model and variants (Chiquet,
-    Mariadassou and Robin, 2021 <doi:10.3389/fevo.2021.588292>) can be
-    used for a variety of multivariate problems when count data are at
-    play, including principal component analysis for count data,
-    discriminant analysis, model-based clustering and network inference.
-    Implements variational algorithms to fit such models accompanied with
-    a set of functions for visualization and diagnostic.
