/**
 * @brief This function learns the topics of words in a document and is the
 * main step of a Gibbs sampling iteration. The word topic counts and
 * corpus topic counts are passed to this function in the first call and
 * then transfered to the rest calls through args.mSysInfo->user_fctx for
 * efficiency. 
 * @param args[0]   The unique words in the documents
 * @param args[1]   The counts of each unique words
 * @param args[2]   The topic counts and topic assignments in the document
 * @param args[3]   The model (word topic counts and corpus topic
 *                  counts)
 * @param args[4]   The Dirichlet parameter for per-document topic
 *                  multinomial, i.e. alpha
 * @param args[5]   The Dirichlet parameter for per-topic word
 *                  multinomial, i.e. beta
 * @param args[6]   The size of vocabulary
 * @param args[7]   The number of topics
 * @param args[8]   The number of iterations (=1:training, >1:prediction)
 * @return          The updated topic counts and topic assignments for
 *                  the document
