Metacat

Updated test so that the query test works. Now all tests should pass, but
still having the cntl-m issue on one server.

New test code for metacat client. Auto-generate id. Query and read from
the inserted document. Still having some problems with the 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.

Add a test case for query method.

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.

Change from assert to assertTrue.
