Missing parameter(s?) from geom_smooth

[dannyparsons]

Colour is missing as a layer parameter for geom_smooth. Can it be added to the geom definition? This would be a good time to check if any other parameters are missing from geom_smooth.

This is a good task for @Ogik99 to do with @maxwellfundi to understand how geoms are implemented in R-Instat.

Great, we will be looking at this today. I remember formula was left out because we did not have editable input textboxes. We can actually revisit that as well.

That would be good to look into. The common ones like colour are most important to get working.
