FHIR Allergy Sample

A FHIR Representation of the Patient with allergies to different substances CDA Sample (from CDA Template Example Task Force)
The CDA sample follows this structure:
<component>
<section>
<text />
Erythromycin Allergy
Bactrim Allergy
Peanut Allergy
Cat Dander Allergy
</section>
</component>
Note: I included these in a feed, since the CDA sample showed them within the context of a section... I thought it would be important to see the list alongside the AllergyIntolerance Resources.
