Started changing time values from NSTimeInterval (double) to NSInteger since there's no need for a double since our data is always only capped at a second
Created a VdotHelper class and moved some helper functions into it
Added a CalculateVDotViewController that is a modal view that appears when the user clicks on 'calculate vdot'. Also moved some methods around and implemented a find vdot method on VdotDataStore.  Need to figure out how the enum should be handled, it's not very elegant as it stands now
