Updated the medication details template to put in the correct contents of doseQuantity based on whether or not med is precoordinated

If med is precoordinated (I.E. RxNorm), doseQuantity should be a unitless number (in our case, "1", since we are giving one dose)
If med is not precoordinated, doseQuantity should be a value and unit, specifying the dose of the drug (I.E. value='75' unit='mg')
Added fulfillment information to medication administration template. Also added a view helper to determine quantity delivered based on precoordination status of code

If code is precoordinated (e.g. RxNorm), the value is equal to the total dispensed quantity divided by the size of a dose, since the value in that case is number of doses, not the amount of medication delivered (I.E. the value is 7950 / 75, which is value='106')
If the code is not precoordinated, provide total amount of medication delivered, based on the quantity_dispensed value and units (I.E. value='7950' unit='mg')
If administrationTiming element is available on the entry, add an <effectiveTime> element with the period data from that timing.
