Library "FunctionProbabilityViterbi"
The Viterbi Algorithm calculates the most likely sequence of hidden states *(called Viterbi path)*
that results in a sequence of observed events.

viterbi(observations, transitions, emissions, initial_distribution)
  Calculate most probable path in a Markov model.
  Parameters:
    observations (int[]): array<int> . Observation states data.
    transitions (matrix<float>): matrix<float> . Transition probability table, (HxH, H:Hidden states).
    emissions (matrix<float>): matrix<float> . Emission probability table, (OxH, O:Observed states).
    initial_distribution (float[]): array<float> . Initial probability distribution for the hidden states.
  Returns: array<int>. Most probable path.
