Return all event registrations in object

[asirota]

The event registrations object requires an event ID to be passed in. Figure out a way to return all event registrations to allow blending with event object. Is it possible to create a new option in event registration to include all event registrations?

If contact Id and event id are left empty use $filter to assemble a list of all event Registration IDs. The $filter field can be used to retrieve a list of all event registration IDs.

Example:

?$filter=id in [1,2,3,4….]

This should be the default configuration of the event registrations object. Selecting by and event IDs or contact ID should be optional.
