[LON-CAPA-dev] Units for Avogadro's number

There isn't a way for an instructor to create a new unit yet.

You can do

<problem>
 <startouttext /> The correct answer is 3 molecules<endouttext />
 <numericalresponse answer="3">
   <textline />
 </numericalresponse>
 <stringresponse answer="molecules">
   <textline />
 </stringresponse>
</problem>

Which isn't exactly like having a unit but does require them to say
molecules.
