* ./katabatic: 

- Change: In Grid/BaseGrid, add an Abutment Box attribute (to facilitate
        segment truncation in Kite::TrackFixedSegment.
    - Change: In Grid/BaseGrid::Axis, when computing a row/column index using
        the graduation table, if the coordinate is exactly on the last
        graduation, return the last GCell instead of "out of bound".
    - Change: In GCell::hasFreeTrack(), AutoSegment::canMoveUp() &
        AutoSegment::canPivotUp() adds a "reserve" parameter to modify the
        amount of wirelength to remains free after the insertion.
