BEP010 iEEG medication status?

Hi!

I was hoping to pitch the idea of adding a place for medication within the iEEG sidecar json:

{
"MedicationsUsed": {
    	"Primidone": {
    		"Dosage": 125
		}
	},
"MedicationUnits": {
    	"Primidone": {
    		"Units": "mg"
		}
	}
}

What are your thoughts on this?

Thanks,
Greydon
