Metacat

This is the merge from the branch WEB_UI_REDESIGN_BRANCH back into the head.
The only files that have been removed are those in lib/style/eml2; other files
that have been cvs removed (only from lib/ and lib/style) have been re-added
elsewhere (i.e. moved from one directory to another)....

Revise some codes.

change return field from "title" to "dataset/title".

Add returndoctype and returnfield for eml2

updated all of the returndoctypes so that emlbeta4 and emlbeta6 will show up in the resultset.

fixed a couple bugs with doctypes that I found while setting up a demo

fixed access control bug. the character data in the sax parser was not getting trimmed and causing problems. also fixed hard coded eml-dataset public id in the web index file

Minor bug fixes following change in style handling. Fixed image locations,
cleaned up main resultset stylesheet.

Updated index page to launch proper initial query.

Modifications that change the package handling behavior of metacat. Package
membership is now determined by an identifier being used as either the subject
or object in a triple. One can not request arbitrary returndocs -- only
those types that have package information embedded can be "returndoctype"...

Modified the license and copyright terms for many of the files. Added
a LICENSE file and a README file in preparation of a distribution.

Various changes to improve consistency of the MARINE and METACAT user
interfaces as presented through the XSL->HTML conversions. Eliminated
one (extraneous) copy of the rowcol.css style sheet in favor of sharing
a single css stylesheet in xmltodb/lib/style/rowcol.css. Modified all...

Updated build process to now use a copy of the source files so that keyword
substitution can ocur before the build. This allows for substitution of
hardcoded values into the source before the compile. Currently, I am
using this feature to do the following:...

-Reorganized xmltodb module to support new install process for the new
linux server (dev.nceas.ucsb.edu). Added "build.sh" shell script that
calls ant withthe proper umask set for installation. Use:

./build.sh install

to post a new copy of the servlet and its supporting files to the install...

rearrange html pages for login and metacat access

fixed html file parameters

minor formatting and display update

update example query in html pages

changed database connection code, added utility class MetaCatUtil.java
