Subject: [PATCH 04/10] Add graphing component for inline/crossline
 visualisations.

The component takes a list of shots and operates in one of these
modes:

* facet="scatter" (default): shows a scatterplot of every shot
  where x is the crossline and y are the inline errors.

* facet="crossline": shows a line graph depicting the crossline
  error along the line, x is the shotpoint and y is the crossline
  error.

* facet="2dhist": shows the crossline error as a 2D histogram.
  The z value is the density (number of samples in the bin) and
  x and y are the bin centres.

* facet="c-o": provided that the shot data comes from a final
  sequence, shows the difference between final and raw positions
  along the inline / crossline axes.

Subject: [PATCH 05/10] Add graphing component for shotpoint timing
 visualisations.

It operates in one of these modes:

* facet="bars" (default): shows a barplot.

* facet="lines": shows a lineplot.

* facet="area": shows a lineplot where the area between the
  line(s) and y=0 is filled with a colour.
