NEON-1238: Restyling the linechart widget to be more responsive to resize events.
NEON-1238: Restructured the visualization widget directive to bind to its index and the list of active widgets to allow them to add spawn new ones or remove themselves.  Also corrected some resizing issues in the linechart.
