An add-on to Luxor.jl.
This is inspired by Visualizing MBTA Data.
Exports three functions:
draw_prominent_axis_labels_update_inkextentdraw_axis_arrowget_config_value
The default look is configureable in the .ini file. Plotting of data is done by drawing in Luxor. The axes are drawn from the drawing origin. `y`` is down, positive rotation axis points inwards.
