This PR changes term from "actions" to "events." In the R package, the biggest issue will be with GlobalActions. The new class in C++ is called "GlobalEvents." The R package should support both in he following way:

• The cpp11 wrapper should call GlobalEvents and be called accordingly.
• In the R file documenting the function, there should be something like the following:

#' @export
#' @rdname globalevents
add_globalaction <- add_globalevent

So that users' code doesn't break with this change. @derekmeyer37, start working on the update of the R package to reflect these changes. I will make sure this PR is merged after the checks are run.
