Log Message:
-----------
Add currentValue (static object) to hold previously selected file/directory.
However there's a drawback. When multiple algorithms use this GUI builder,
the selection will show up cross those multiple algorithms. Currently we 
can't support preserving the previous selection for each algorithm separately.
