%description
Implements the 'bayesRecon' probabilistic reconciliation methods within
the 'fable' framework for hierarchical time series forecasting. Bayesian
reconciliation (bayesRecon) methods are accessed via the 'reconcile' verb,
following 'fable' conventions. For methodological background, see Corani
