Finish off the data types, and tables and byte arrays.

Actually display the data as a table.

Implement refresh.

Add CDDL header (assuming prtpicl.c has it...).

Ideally we would actually pass the type back into java, and pass some
form of the raw data, and format it there, rather than converting it
into s string inside jni. But it depends what we're going to use it for
- if it's just the browser, then we're probably OK.

Implement a search facility, so that you can search for a regexp
match. Both for nodes and properties.
