PM_PartLib.py
The PM_PartLib class provides a groupbox that contains the partlib (any user
specified directory). The parts from the partlib can be pasted into the 3D
workspace. The selected item in this list is shown by its elementViewer
(an instance of L{PM_PreviewGroupBox}). The object being previewed can then be
deposited into the 3D workspace.

History:
The Partlib existed as a tab in the MMKit of Build Atoms Mode. (MMKit has been
deprecated since 2007-08-29.)
