update for marginals
implementing Dirichlet particle filter
add double
add Dirichlet particle filter
put title texts of graphs in latex files instead of embedding PDF files
import from ASA266 at http://people.sc.fsu.edu/~jburkardt/cpp_src/asa266/asa266.html
add codes for maximum likelihood estimate of dirichlet parameters
add variance at each frame
visualize variances of alpha (drichlet parameters)
online estimation of alpha and beta with log-sum-exp trick (still not stable when N is large)
online estimation of alpha_hat and beta_hat, and c_hat
add MarginalOnline
