0.2: first public release, circa 2000

0.3: Sanitized the source to make it compile with newer jdks, some
documentation on standalone operation.

0.31: First steps towards gaucho, a nicer standalone Dexter

0.32: Fixed a stupid bug in findCB used by the Recognizers (returned
junk when black region border was==blackThresh).  Added an incredibly
nasty hack to keep the popup window from sticking out of the screen
on top.  Tips on how to do this sanely urgently solicited.

0.39: Added ScriptImageGetter and Gaucho.  I should be replacing
some error messages to the console with graphical alerts.  Won't
be happening unless someone bugs me, though.

0.40: Results are now given sorted by abscissa values.  In doing
this, I moved Datapoint to a class of its own and did a cleanup of
DExtractor:makedata_orth.  This is the first public release with
some support for local extraction.

0.49: Began code cleanup at a few places.  Some fixes to dexter_getImage
to make it actually read PDFs (but it's still advisable to manually convert
PDFs to Postscript before using Gaucho).  We now do Java 1.5 type 
collections.
