Add Support for Pattern Value Constraint with $this in the Path

support canonical pattern value constraints

We generate a constraint = "generated-C4BB-Organization-1: Constraint violation: meta.where(lastUpdated.exists() and profile = 'http://hl7.org/fhir/us/carin-bb/StructureDefinition/C4BB-Organization%7C1.0.0').exists()"
should this be = or an in http://hl7.org/fhirpath/#in-membership
Currently, we say the following is an error, however profile is an array...

{
  "resourceType" : "Organization",
  "id" : "OrganizationProvider1",
  "meta" : {
    "lastUpdated" : "2019-12-12T09:14:11+00:00",
    "profile" : [
      "http://hl7.org/fhir/us/carin-bb/StructureDefinition/C4BB-Organization",
      "http://hl7.org/fhir/us/carin-bb/StructureDefinition/C4BB-Organization|1.0.0"
    ]
  }
}

they had a constraint on the number of profiles, I'm opening a JIRA issue for it

What they're trying to say here is that exactly one of the profiles must be http://hl7.org/fhir/us/carin-bb/StructureDefinition/C4BB-Organization%7C1.0.0.
The profile element itself is 1..*, its just the slice with this pattern that is 1..1.

Net: I think this is solely our issue and I think the IG is just fine.

hum... I thought this asserted that the canonical pattern has to be...

@JohnTimm I think you've already implemented this?

I've already tried this out.
