Metacat

Updated more tests on session reuse. Made the http calls set the sessionid
explicitly rather than relying on cookies being passed around statically.
Still need to modify HttpMessage to get rid of the static cookie.

New versions of the Metacat client API that allow access to the sessionId
so that a session can be reused over several different instances.

Fixed the sessionId handling code to now properly return the sessionId
in the login response message. Updated junit tests to test this issue.

Modified metacat to now provide the session identifier in the response

of that class that is found in the utilities module. This may cause some...

Implement logout method.

Add a logout method.

Implemented the update and delete methods in the interface, along with tests.

Implemented the "insert()" method and wrote a test to test it. The new test
depends on the property "newdocid" be set to something unique in the build.xml
file so that the insert will work properly. Probably need to fix this to be
some kind of autoincrement counter or random number so that it can be run...

Refactored to use IOUtil routines. Reformatted for within-file consistency.

Implement query method.

Add metacatinaccessible exception for query.

Implemented the 'read' API call. Some more to go...

Wrote the login() function, the first of the series of API calls for
the metacat client to be implemented. Also wrote a test class to
test the API functionality.

Added a new subpackage (edu.ucsb.nceas.metacat.client) which is a client
access library for the metacat. There is an interface (Metacat.java) that
provides simple access methods for the main metacat functions. This is to
support clients like Morpho and others that want to programatically access...
