This script aligns two topic models produced by MALLET (http://mallet.cs.umass.edu/)
Reciprocal topic pairs are reported with JS divergence measure.
Reciprocal pair (i,j) is defined when the distance of topic i from the first model (M1) and topic j from the second model (M2)
is minimal for all pairs (i,k) for k in M2 and (l,j) for l in M1 (best match for both topics).

This is useful for:
1. Qualitatively comparing different modeling parameters or algorithms
2. Identifying stable topics when running a few times
