Description

Use the vectorDotProduct function to compute the vector dot product of two arrays.

The vector dot product is the sum of the pair-wise product of matching keys from each array. It is equivalent to the following:

    put 0 into runningTotal
    repeat for each key currentKey in firstArray
        add firstArray[currentKey] * secondArray[currentKey] to runningTotal
    end repeat

The names of the keys in firstArray must be the same as names of the keys of secondArray.
