create sensible $print functions for the different R6 classes about simmer HOT 4 CLOSED

Some work on this: 9ee806e. I don't know if you had in mind something... nicer. 😄 I didn't feel very... creative, so I confined myself to the trajectory output format.

Note: now Trajectory$print() points to Trajectory$show(), and therefore create_trajectory() and create_trajectory() %>% show_trajectory() do the same.

It's already a lot better than the raw R6 show function 😄

What about deprecating the show_trajectory function? As simply printing the object returns the same output, I don't really see use for the show_trajectory func.

+1. How do we do that? Simply by specifying in the docs "(deprecated)"? Additionally showing a warning?

Oh, I see how it's done.
