The Alpha constructure function returns an R6 Alpha_
class which feeds sanitised prior or initialisation values for alpha into the model.

Implements a non-parametric source attribution model to attribute
cases of disease to sources in Bayesian framework with source and type effects.
Type effects are clustered using a Dirichlet Process. Multiple times and
locations are supported.
