      Refactored model specification · e52283b6
      Chris Jewell authored
      Changes:
      
      1. Created a TFP JointDistribution to represent full probability model;
      2. Renamed CovidUKStochastic --> DiscreteTimeStateTransitionModel;
      3. DiscreteTimeStateTransitionModel now inherits from tfp.Distribution.

      Re-wrote discrete_markov_log_prob to batch the call to
      tfd.Multinomial.log_prob to avoid lgamma time.

      1. chainbinom* file and methods renamed to discrete_markov* files and methods.
      
      2. Implemented batched hazard rate calculation, adding functions to automatically broadcast rates to the Markov transition rate matrix.
      
      3. Implemented test simulation and MCMC algorithm.
