New distances.

Fix calculation of log likelihoods for BaumWelch learning

- Removed unused variable oldLogLikelihood
- remove re-initialization of newLogLikelihood to -Inf,
    which caused only the last sequence in a set of sequences
    to be used in the fitness calculation!
initial implementation for   Kumaraswamy distribution
removed ternary operator and replaced with an IF block.  added parameter attributes and argument range checking for constructor

Fix calculation of log likelihoods for BaumWelch learning algorithm.
Adding more configuration options in clustering algorithms; updating bag-of-words to avoid computing costly cluster informations after the clustering is done.
