public class RelocateHierarchy
extends Object
Given an input DCP, a hierarchy prefix (empty string to match entire design)
and tile column/row offsets, move all matching cells (and the PIPs that
connect between such cells) by this tile offset.
Specifically, the SiteInst associated with a matching Cell is relocated.
Should this SiteInst contain any Cell-s not matching the hierarchy prefix,
relocation will fail.
