Will add a 'warning' constraint on ElementDefinition if there is a fixed value defined for a complex type saying "For complex types, consider using a pattern rather than a fixed value to avoid over-constraining the instance."

We will also adjust the IGPublisher to spit out an equivalent message for this when dealing with profiles created against prior versions of FHIR.

Suggest that fixed values on complex types should instead use patterns so as not to overconstrain.
