New module: CHADS2 score

I’ve added the CHADS2 score which is the often used (and clinically validated) score to estimate stroke risk in non-valvular atrial fibrillation. This mobile app also includes the newer CHA2DS2-VASc score. It has been added to both the Cardiology and <a href=" published here.php/neurology/”>Neurology sections of this site.
On a tech note, this is the first time I am using NSB/App Studio’s new version which incorporates the jQuery Mobile framework. The checkboxes and controls are very nice and this gives the apps a new look.
