SMM — Improve Observations

Source: Alain Picard, Benchmark Consulting
Summary:
This is a follow-up to continue improving upon the Observation class. In order to allow observation to be the starting point of a request to perform measurement and be the collector of those measurements. The changes here address these short-comings.

Discussion:

Summary of change:
· Added a new "ObservedMeasure" class, a generalization of SmmRelationship, with the following associations:
o Add named relation of measure[1] from ObservedMeasure to Measure
o Owning the measurements having been calculated for a specific measure
· Added a new association to the Observation class
o observedMeasures, owning the ObservedMeasure instances for an observation
· Remove relation from Measurement to Measure as it is now being replaced.
· Add named relation of requestedMeasures[0..*] from Observation to SmmElement (with constraints)
