This function allows you to export the events for a project

It is not sufficient to make the project a longitudinal project. The
project must satisfy one of two conditions: 1) have at least two arms and
one event defined; or 2) have one arm and at least two events defined. If
neither of these conditions are satisfied, the API will return a message
such as ERROR: You cannot export arms for classic projects
, an
error message that isn't as descriptive of the nature of the problem as
we might like.
If the project information reports that the project is not longitudinal, a data frame with 0 rows is returned without calling the API.
Please refer to your institution's API documentation.
