$5.$ Read in the next row of values from the file

Check to see if the new ubitname already exists in the ubitname vector

If the ubitname already exists, sum scores together in the score vector

Else, add a new entry into the ubitname and score vectors

Repeat steps $5$ and $6$ until the file ends
