# Go through the files and extract the summary statistics for each run.
# This is useful to see that BioGeoBEARS ML searches produce the 
# same log-likelihoods (LnLs) and parameters inferences as LAGRANGE.
# (The exception seems to be that C++ LAGRANGE has a different LnL and
#  slightly different parameter inferences in stratified analysis WITH
#  a varying dispersal probability matrix, i.e. dispersal mask, i.e. "Dmask"
#  in the code. It appears that perhaps the Dmask is being given a dual use in the
#  code -- dispersal probability multiplier, and ranges allowed, and the latter is
#  used to zero out the likelihoods of prohibited ancestral states.  However, the 
#  rate matrix should do this automatically, if EXPOKIT matrix exponentiation is being run in 
#  the correct direction; if it's not, you may have to manually zero out impossible ancestral
#  states.  This code zeroing out impossible ancestral states is blanked out in the C++
#  code for dense matrix exponentiation.  Perhaps (?) this allows more ancestral states,
#  thus higher log-likelihoods.
