Framework coverage map

Pick two frameworks — the right one can be a control set or the CWE weakness pillars. See how well the left one covers the right — colored by coverage, with the per-control mix. Click a left block to see where it maps; click several to pool them; click a right block for the inbound view; one-of-each opens the control-level mappings with both stored directions. All coverage is our own direct, authored mapping.
