Create rule: Each ScheduleTimeline must have at least one ScheduledInstance with a Timing of type "fixed reference" #122

Create rule defined for #108

This should be split into two rules:

Each ScheduleTimeline must have a ScheduledInstance (using new cross-class joining)
Among the ScheduledInstances for a ScheduleTimeline at least one should have a Timing of type "fixed reference"

This is more complicated because ScheduledInstance is split up as ScheduledActivityInstance and ScheduledDecisionInstance - either one of which could be the necessary "fixed reference"

The first part of this check ("Each ScheduleTimeline must have a ScheduledInstance") is a duplication of part of the checks defined for #110 and #158).

In order to perform the second part of the check, we need a definition of "have" in "should have a Timing...". Is it the timings relationship or the relativeFromScheduledInstance relationship that should be used as the basis of this check?
