Heracles first release

This is the first Heracles release.

It includes all the base features in Heracles. It uses at least v1.0.0 release of WebAPI.

To add additional WebAPI configs, you can use Olympus, or edit the ohdsi_services array in build/js/Heracles.config.js, e.g.

var ohdsi_services = [
    {
        name: 'Local',    
        url: 'http://localhost:8080/WebAPI/'
    },
    {
        name: 'Public',
        url: 'http://api.ohdsi.org:80/WebAPI/'
    },
    {
        name: 'NLP01',
        url: 'https://nlp01.regenstrief.org:8443/WebAPI'
    }
];
