Commit Message

Compresses factor graph binary files with bzip2

when grounding, and decompresses on the fly with bzcat when running the
sampler.

This cuts a 2MB (2300279 bytes) factor graph down to 184kB (184224 bytes)
(one produced by the test with spouse_example/ddlog app) with negligible
impact on runtime (or even faster!).

```bash
groundingTime() {
    local log=$1
    tstart=$((sed -n '\@process/grounding/.*/dump@{ p; q; }' | awk '{print $2}') <$log)
    tend=$((sed -n '\@LEARNING EPOCH 0@{ p; q; }' | awk '{print $2}') <$log)
    echo $(date --date="$tend" +%s.%N) - $(date --date="$tstart" +%s.%N) | bc
}

$ # dump from database and load by sampler without compression
$ groundingTime test/postgresql/spouse_example/ddlog/run/20151221/040549.120506000/log.txt
3.363981000

$ # dump from database and load by sampler with compression
$ groundingTime test/postgresql/spouse_example/ddlog/run/20151221/034709.985065000/log.txt

```

Note that gzip has a 4GB limitation, so bzip2 was used despite its
higher computational cost.  xz may be another good candidate to consider.
