/*! \brief The Unit Test tool for schema browser "second tab" (see toBrowser).
The tool area is split into two widgets:
PackageList (1) - it's the lost of package/function/procedure members,
e.g. all package's procedures etc. When user chose one of these members,
the test script is created in the worksheet (2).

This tool is available for Oracle only in this release (see canHandle()).

What is the Unit Test Script? The anonymous PL/SQL block with the following
structure:

DECLARE
    -- declarations of IN/OUT parameters
    foo number;
    bar varchar2(22);
BEGIN
    -- definitions of parameters
    foo := 1;
    bar := 'a';
    -- calling requested unit
    MYOWN.COOLPACKAGE.FOOBAR(
        foo => foo,
        bar => bar
        );
    -- printing of the results
    sys.dbms_output.put_line('foo: ' || foo);
    sys.dbms_output.put_line('bar: ' || bar);
END;

\note: All results are printed to the SERVEROUTPUT.

\warning: It can handle only basic data types currently.
No PLSQLdata (record of etc.) supported yet.
