Remove this note describing QUICK in section 1.3.2.4: 

Note that QI-Core is intended to be a FHIR-based rendering of a quality-focused logical model called QUICK (Quality Information and Clinical Knowledge). However, the QUICK model is still in development, so the QI-Core profiles are currently built directly as a FHIR Implementation Guide. To support the goals of the QUICK logical model, the QI-Core implementation guide includes an author-focused view of QUICK, the QUICK logical view. See the Relationship Between QUICK, the QI-Core Profiles, and FHIR discussion in the QI-Core implementation guide for more information.

QUICK is no longer referenced in QI-Core.
