Arguments

K	number of topics
V	vocabulary size
doc.size	number of words in each document
J	number of collections
collection.size	number of documents in each collection (a list of J elements)
alpha.vec	a set of values for document-level Dirichlet sampling
eta.vec	a set of values for topic Diriclet sampling

## Generates documents with given parameters

K                  <- 4
V                  <- 20
alpha.h            <- .2
eta.h              <- .5
doc.size           <- 80
num.docs           <- 40 # number of documents in each collection
ds.name            <- paste("synth-K", K, "-V", V, sep = "")

ds                 <- gen_synth_corpus2(K, V, num.docs, doc.size, alpha.h, eta.h)
