Data model enhancements

Data model enhancements support new Clinical Performance Measures integration.

• Added all Clinical Performance Measures required fields from Universal File Spec that were tied to Encounter and Cost Detail tables and made them part of standard Axiom Decision Support data model.

• Fixed a significant data model issue within Axiom Decision Support related to sequencing of ICD Diagnosis, ICD Procedure, and CPT codes caused by an additional composite key, which allowed for the duplication of sequence ones.
