Added in tooltips to the popChart. Also changed denom to be based on anti-numerator since it didn't make sense to have DENOM be different in two places
Per discussion with Liam, removed calling popover twice and moved data-container into the elements themselves for cleaner code
Removed Bootstrap dependency from d3 code by moving popover call to Thorax view. Also scoped down the popover call to only be inside .pop-chart class elements
Changed how scoping was done to be more in line with Thorax patterns
Added in logic to only do the popovers when the measure is populated
Added in logic to pull the performanceDenominator in from the model so that the chart and the fraction display were more in sync
