Replace line plots with bounding boxes (#12)

* move spacing to inside the canvas to make room for annotations

* show plot cell borders, and allow mouse selection of plot cells

* draw mid-res plots

* highlight mid-res cells in plot

* fix fitChildren to avoid floating point precision errors that choose the wrong stretch scale

* fix mock data at bottom two levels to not break floating point limit

* add count aggregates to mock data

* add path adjacency functions since plots have to draw lines to adjacent points are still visible on the edge of each node

* add adjacent points to levelData
