Transect information in title

[jwarner8]

What problem does your feature request solve?

Currently when transects are plotted, there is no information on the start and end coordinate tuple. This information is captured at the CYLC level, but is not contained within the cube itself. To be able to expose this information in the plot operator, we probably need a solution in the transect operator that stores the coordinate information as an additional attribute. Then we can access the information when plotting.

If you don't mind it not being in the plot itself, you can add it into the title or description field of the recipe, and then it will show up on the website.
