* ./kite: - New: In BuilPowerRails & BuildBlockage, specific support for chip-level design. The Alliance "top chip" design hierarchical structure is hard-coded. Top level POWER/GROUND/CLOCK nets must always have the <vsse>, <vdde>, <ck>, <vssi>, <vddi>, <ckc>, <cki> names. Specific method to get trans-hierarchical root nets, espcially in case of global ones (POWER/GROUND). Clock is *not* global. Some correction in the manner obscured tracks are computeds. - New: ProtectRoutingPad module that perform a more clean work for protecting unused RoutingPad. - Bug: In BuildPowerRails, uses stable_sort<> instead of sort<>, which causes unexplained core dumps (seems to try to perform a comparison using the "end" pseudo element). Already occured in Knik, no explanation other than a STL bug. - Change: Slight changes in the weights to move up. Now needs a full empty track instead of a half one.
