better formatting
complete the fix for #21
add a regex for arya... still VERY doubtful of this
make the regex weaker
use a different example for unknown
most liberal pattern for Arya. Also, fix glaring error in AddExactVrtta when | etc. are allowed.
Add print options. Fixes #29

The options added are
  --print_identified_verses {none,brief,full}
  --print_unidentified_verses {none,brief,full}

The default corresponds to
  --print_identified_verses=brief --print_unidentified_verses=full
pick one that really has no issues :)
start moving towards the better names. Right now, everything is still a regex.
(m) rename
(m) do the ^ + ... + $ beforehand
Up to 10x - 50x improvement, with re.compile!

Perf stats:

Without compile:
8s for bharst_u.htm, 32s for govass_u.htm
With compile:
0.8s for bharst_u.htm, 1.2s for govass_u.htm

And after adding the HUGE Arya regex:

Without compile:
48s for bharst_u.htm, 25s for govass_u.htm
(Yes govass_u.htm is faster, probably because Arya is checked first and matched earlier.)
With compile:
0.95s for bharst_u.htm, 1.35s for govass_u.htm
