Analyze Page - Adding Cumulative Toggle

Similar to the cumulative spend through the month on the main dashboard, add functionality to the Analyze Page where you can flip the chart to cumulative mode over the time frame you've selected. This would allow users to see a spend or earnings profile, cumulatively, over a period of their choosing. Bonus points if you also have the ability to pivot this cumulative chart by category (i.e. see cumulative Earnings and cumulative Spend as separate lines on the same chart). This was one of the features that people loved during the Mint days!
