Documentation for schedule event says it sets the schedule id but that is not what happens

[b1conrad]

Documentation for the schedule library strongly implies that the postlude statement setting clause binds the ID (a string) of the scheduled event. But, in fact, it binds the map containing (among other things) the ID.

Documentation also shows the action to remove a scheduled event expecting the ID as a string, which works, but it also works passing in the entire map.

This leads to some tricky coding needed in some cases (for example, this commit in another repo). We should decide how to deal with this.
