Open Web App for concepts

The goal of this epic is to migrate the old concept pages into a new AngularJS and REST based interface, which we will distribute as an Open Web App.

We will be developing using OpenMRS Platform 1.11.5 and the webservices.rest module in the latest SNAPSHOT version. Later we will integrate the app into OpenMRS Reference Application 2.4.

Please refer to https://wiki.openmrs.org/display/docs/Open+Web+App+Development+Workflow for setting up your development environment.

REST resources are exposed by https://github.com/openmrs/openmrs-module-webservices.rest
