rename "exposure event or process" to "exposure of organism"

[wdduncan]

In ECTO, there is an exposure event class. However, due to the RO import, the class exposure event or process exists. It would be helpful and less confusing if ECTO used the same class as RO for these events. Would you be willing to change label for exposure event or process to simply be exposure event?

I am also going to see exposure event can be added to COB.

I don't have any objections but this is really up to @diatomsRcool.

Another suggestion may be for RO to use the ECTO class exposure event for the domain constraint. However, that may break existing usages.

We should obsolete the RO class and use an ECTO or COB class (not ExO). classes are only in RO as placeholders.

I'm fine with changing the label.
FYI - If memory serves the "event or process" was used to emphasize that an exposure event was a type of BFO process. There was a lot of discussion about event vs process.

COB has added an exposure of organism class.

Waiting on new release of COB before using this class.
