Class MedicationAllergyModifier

[Manu Sikka]

I ran text in the CAS which included medication which the patient was allergic 
to but the class MedicationAllergyModifier did not catch it.  It caught the 
medication which is good but it is concerning that the medication was not 
caught in the context of allergy, but as a general medication similar to what 
the patient takes.  In this case it was a penicillin allergy.
