Add a resource used by the activity.
This method tries to be as permissive as possible. It accepts a string which might be a synapse ID or a URL,
a synapse entity, a UsedEntity or UsedURL dictionary or a list containing any combination of these.
In addition, named parameters can be used to specify the fields of either a UsedEntity or a UsedURL.
If target and optionally targetVersion are specified, create a UsedEntity.
If url and optionally name are specified, create a UsedURL.
It is an error to specify both target/targetVersion parameters and url/name parameters in the same call.
To add multiple UsedEntities and UsedURLs, make a separate call for each or pass in a list.
In case of conflicting settings for wasExecuted both inside an object and with a parameter, the parameter wins.
For example, this UsedURL will have wasExecuted set to False::
activity.used({'url':'http://google.com', 'name':'Goog', 'wasExecuted':True}, wasExecuted=False)

location and provenance of all downloaded files).
