the class EventManager method getEventsFromTag.

/**
 * Gets the live events posted to this manager which have a tag greater or equal to the specified tag.  Events are coalesced
 * where possible.  That is, if event E1 is posted at time t1 and event E2 is posted at time t2 and E1 and E2 are
 * equal then a list containing only E2 will be returned.
 * @param fromTag The tag that denotes the point after which events will be retrieved.  Not {@code null}.
 * @return The list of live events that happened since the specified tag.  Not {@code null}.
 * @throws NullPointerException if {@code tag} is {@code null}.
