Issue #, if available:
Description of changes:
This PR creates a new analyzer called RatioOfSums. It aggregates and sums 2 separate columns, then divides them.
For example, imagine a baseball dataset that contains hits and total at-bats, with a row for every player in every game. If a player's batting average (total hits/total at-bats) changes by more than 0.2 in one week, an error or warning could be given. Another example is a % of total calculation in a table that has many rows with facts val1, val2, val3, total, and we want to ensure that val1's percent of the total doesn't change more than X in a given time period.
