Review comment:
       Thanks @gsmiller! I added the code below in getDimValue to exit the 
function earlier if these conditions have been met.
   `
   if (dimConfig.hierarchical == true || (dimConfig.multiValued && 
dimConfig.requireDimCount)) {
         return counts[dimOrd];
    }
   `
   But if I add the same conditions to `getChildOrd`, then it would be a 
duplicate check when calling getChildOrdsResult from `getDimValue`. 
   
   GetPathResult is another method that calls `getChildOrdsResult`, and I think 
the first condition in the return statement plus the existing check in 
`getChildOrdsResult` handles the conditions. Please correct me if I am wrong. 
Thanks again! :)
