A1C chart still WIP

Added initial A1C chart that displays all a1c values from all visits,
hover on a data point to see the values.
Added accordian to display a1c chart and plot of bmi (still need to
implement)
Added hover feature to flot chart
Added corresponding files for flot charts
Added new fonts for accordian use
Fixed minor bugs in test (missing a few semicolons)
*** Still need to add the ability to pick and choose which visits to
view in the A1C plot
