Cohort Charting demo

Looks like there's finally something nice to show. A demo page will be made available to show some possible interactions between cohorts, and concept charting. Basically, one is able to pick a concept and have it graphed for a set of patients.
It's not yet a stable OpenMRS component, but still a very promising one.
Drop by #openmrs this Wednesday around 3pm EST if you'd like to know more...
