Notes de version:
v4
Changed divergence strength/degree calculation to use the angle of the divergence line divided by 90 degrees (as opposed to the % change in the indicator value). This will keep the unweighted strength value between 0 and 1 for the indicator portion of the calculation, which is desirable because different indicator series can have wildly different ranges.

When calculating the divergence strength on an indicator, Scale the X coordinates to a range similar to the Y scale (X and Y scales should be on the same order of magnitude for the angle value to be meaningful. e.g. if ΔY is 10,000,000 and ΔX is 12, the angle will always be very nearly 90 degrees, which makes for a meaningless value)
