Update javadoc and documentation on maptileservlet and MapTileSets.
Ignore generated javadocs.
Fixed Geo.intersect, reverted to previous algorithm.  Added
MapTileRequester and modified factories to use it.  MapTileLayer
implements MapTileRequester.  OMScalingRaster lastProjection less
reactive to generate calls.  FileUtils updated to use SwingUtilities to
get chooser called made in event thread.
Fixed CADRG getScale method.
Changes for Tag 5.0.2
Removing @Override markers
Moved isEmpty() to length() != 0 to preserve jdk1.5 compliance.
Updating version number in master to 5.0.3b
Remove logger.info message in ImageServer.
See CHANGELOG.  Added delete() to FileUtils.  Modified rendering methods
in OMGraphics to use synchronized getShape and setShape methods. 
Updated and improved SimpleAnimationLayer and deleted AnimationTester
(obsolete).  Updated LayersMenu to use object lock for layer checkboxes.
Updating version number in trunk to 5.0.4b.
Improved how the WholeWorldTileHandler detects source directory parent,
which gets removed from jar file path during creation.  It is also
tested only once, instead of for every file.
Updates to ommaptileservlet, where tileSetProperties directory is
defined in web.xml file, can be located anywhere, and contains
properties files defining MapTileSets. More tileset definition examples
added. Updated MapTileMaker to be EmptyTileHandler, enabling runtime
tile creation on demand. MapTileLayer has GUI button to delete local
file cache. DebugMapTileFactory added that just supplies empty tiles
with location/zoom info as labels, draws tile extents, too.
Added code that creates a little catalog at the top-level of the context
of the servlet.  The catalog lists the available tile sets, with links
that will display the tiles in a leaflet map.  So, if you point your
browser to the host:port/ommaptile, you get the catalog.
Fixed off by one error when calculating extents.
Update the sample leaflet map to have layer controls - so when the
catalog choice still brings up the map tile set of choice, the map can
be switched to any other tile set, too.  This might help locate tile
sets restricted to a specific area.
Polyline/Polygon M types were being sent to Z build methods.
Updated
Fix for Geo.azimuth(Geo), the angles returned seem a little off the
further you get from the equator.  Replaced the internal algorithm with
the version from GreatCircle.  Although the GreatCircle algorithm is
based on the spherical model, the Geo version is corrected for the
ellipsoid model.
Updated the GUI in the MapTileLayer to only present the delete cache
button if the MapTileServer is a ServerMapTileServer.  This prevents the
layer from deleting a set of tiles without having access to another
copy.  Also removed a reference to a proprietary layout.
